Scrolling thumbnails.....slow, jerky and pixelate

So I updated to 1.5.......I like many of the new features, but I can't figure out where all this new speed is supposed to be in the program??
I have my Aperture Library on an internal 300GB SATA Maxtor 7200 RPM with 16MB Cache. My library is roughly 33GB (almost 4000 photos). 90% of the files are .cr2, the other 10% are .crw. I have a project folder with 2920 photos. I deleted all the previews for the project.
Everytime I scroll through my thumbnails they pixelate, they jerk down the screen trying to catch the scroll wheel of my mouse and then take several seconds to clear up once I stop and they catch up.
So here's the rub...
I have 128,000 photos of all types and on multiple external hard disks, in my iView Media Pro app. Yet, I can scroll through all of these thumbnails without a hitch. I can stop and reverse direction and the thumbs will follow my mouse. My CPU doesn't start maxing out and my fans don't all start whirring (a symptom Aperture will have if I keep scrolling without a break).
Do I have Aperture setup improperly? Are the Aperture thumbs a better quality than the iView thumbs? If they are, is there a way to lower the quality? I don't need hi-quality thumbs, only photos. What gives??
TIA for any help.

kgelner,
Thanks. I do know of the sizing of the previews and the different settings for each project. I turned off the New projects create previews (got tired of listening to my fans all day) and I only create previews for the projects I may later want to use in iDVD, iWeb etc.
However, I deleted all the previews in said project above to see if I got any performance boost with my thumbs. It's no better than 1.0!?! Sometimes as I scroll, I'll see a photo or section of photos I want to view so I'll stop scrolling. But the thumbs haven't caught up with my mouse wheel, so it will skip ahead several rows of thumbs. Then I have to scroll back. This is very annoying. Again, I don't have this problem with iView. It stops on a dime and all the thumbs are crystal clear as I scroll.
When they show their videos on the Apple website, they don't seem to have this problem with their thumbs. Is this due to the fact that the project they use for an example contains only 250 or so photos??
Do you have a lot of pixelation with your thumbs??? If so, then I know it isn't just me. Perhaps Apple is running their Aperture program on the VTech supercomputer?? I heard it was dismantled. Maybe they will loan it to me so I can put all my photos in Aperture and be rid of the Beach Ball once and for all.

Adobe Flash Player slow, jerky, and I NEED HELP A.S.A.P.

Hello everybody, and how are you all doing on this wonderful Friday?
Today after doing research on the support website for Adobe ShockWave flash player, I'm here as a last resourt.
Allow me to explain the issue!
WARNING:
THIS IS GOING TO BE EXTREMELY LONG, BUT I NEED HELP VERY VERY BADLY!!
I've waisted people's time because of this issue.
I'm using an HP Windows 7 Laptop with latest version of Windows 7!
I have Adobe ShockWave 11.7 the LATEST VERSION and It is a great program.
However in one of my simulators which is a V500 Evita Ventilator simulator from the company Drager, the performance is HORRID, and when I say horrid, I mean HORRID TIMES 30 and then some.
Keep in mind that this has been tested by the company on other computers, and it works just fine, however on mine the waveforms and data is choppy, slow and what it will do is it will be working smoothly one second, the next second It lags and then catches up, then lags again, and It basically drags along miserably. I used this program online and then when I contacted Drager the owners of the simulator, they thought I get a DVD of the simulator. THEY GAVE IT TO ME FREE OF CHARGE. I got it, and It was still slow and Jerky. I had used Google Chrome to use the simulator online HOWEVER, when I used the DVD, It was still slow. I have a LOAD of computer space, and have tried uninstalling Adobe Shockwave, Reinstalling it, then doing that several times. NOTHING. NOW WHAT??
I'm desperate right now. When I say DESPERATE, THIS HAS GOT TO BE FIXED AS SOON AS POSSIBLY POSSIBLE.
ASAPP!!!!!!!!!!!!!!!
Is there some setting I can adjust?
Or SOMETHING???
The thing is other things that require Adobe Shockwave work just fine. I use a lot of simulators.
Its just this simulator.
PLEASE RESPOND!!
THANK YOU, and God bless.

XML scrolling thumbnail, image loader, & Buttons [halfway works]

Intro:
I started a flash-based website a few years ago. Back in 2006 I was able to get a xml scrolling thumbnail, image loader to work without a glitch.
For numerous reasons I had to put the project on hold until now. [one was that my 30 day trial of flash expired and only recently was I able to purchase the Adobe Web Suite CS4 as well as a new computer which could run the apps.]
Last Friday saw a bump in the road in the development of my site as two, rather straightforward task, turned into something short of a nightmare as I have been unable to get past these two, seemingly, relatively simple task.
I have posted in 4 other flash forums the issues, in detail, that I am facing - and have quite a bit of interest/views in the topic as the numbers suggest - yet no response/answer as of yet. [Which confirms other messages I have seen which seem to state that working with buttons has become increasingly difficult with the newer version of flash - something Im a bit surprised with actually from Adobe. - I would have thought there would be a palette where you could set parameters...]
Screenshot of Site/Timeline:
Before getting into the two questions I have, I would like to post an image of the site as it looks whenever an swf file is saved out, as well as a piece of the timeline in the back for reference.
Issue #1
As of now when the swf file is saved out you get exactly what you see above:
a: A scrolling thumbnail
b: ...which loads a large image when clicked on it - PEFECT...
BUT...
1a: I need for the buttons to load in this action, not for it to just load on its own.
[i.e., the silk_paintings gallery is what is open, so I need the "silk_paintings" button to call up this action]
note: Initially I had attacked this problem by taking out the actions layer you see above and applying it directly to the individual buttons with some crude MouseEvent Listener/Handerls... that did not work - at all.
Im sure it may be "easier" to make an array out of it, but with my coding level it may be "easier" to apply it to the buttons.
1b: How I currently see it, I would take the xml-list and duplicate it for the number of galleries I have.
[I would then re-name the xml-list to reflect the name of the galleries they are to represent, i.e. "silk_paintings"]
[also, I would have to rename the folders to "thumbnails1,2,3, etc., & "images 1,2,3, etc"
From there I would duplicate the actions and paste it into the buttons, changing the xml-list name to that of "silk_paintings", etc., as well as write in the MouseEvent listener Handler to make it work. [ah, ha, but what is that magic phrase, I have tried to implement various code from other tutorials, and all in vein.]
Issue #2
At this point I would be tickled pink just to get this to basic function to work.
However, once the buttons are working and calling up the xml, etc., then I need the buttons to stay on the semi-transparent blue color it is whenever in the 'hit' state. [note: NOT pictured above.]
With the way the buttons are currently set up, and with wanting to use scripting to get them to interact with the thumbnail gallery, it will have to be some miraculous code to tell that button what color to stay as whenever its clicked, and of course it going back to white when another button is clicked.
Conclusion:
Since this is an Adobe Forum I would like to make a few additional statements in hopes that the developers, etc. may take heed.
Adobes products are not cheap, and when I went to purchase the websuite I went in as a designer needing a program as not to need to program.
I understand the flexibility that coding gives, but something as simple as linking buttons should not be in the realms of rocket science. [yes, for many its not...but my brain just does not operate that route despite all the tutorials thrown at me.]
Again, it would seem that there would be a button panel where you could drag options like scrolling thumbnail slider, loader, and then parameters would come up. [much like Apples iWeb. - but before the argument of one being pro and the other for non-pros, I see it differently. Software should not be the limiting factor in how flexible you can design, or rather ones lack of programming shouldnt be. With all the talented, and I say this in all humility and honesty, programmers working for Adobe, Im sure something could be programmed like what Im asking for.]
note: Director is a good example, back in 1997 I knew nothing of multimedia and in one week I had assembled a portfolio, clicking buttons, speech, movies, and all. - and no, I dont have the money to buy more software!
At this moment I am at the mercy of someone who reads code like its a nighttime tale they are telling their kids, and who can see the exact issue I have and can share the appropriate, correct code. [as I have noticed, it has to be on target - naturally - but this target changes with just a slight change in the design.]
Thank you,
peace
Dalen
p.s.
The actionscript: [note: This is only the current working/good code that Im trying to get the buttons to call up.]

The issues with the buttons calling up the scrolling thumbnail panel have been resolved, as well as keeping the buttons in their hit state once clicked, thanks to Rob.
Those that have been following this thread, or stumble upon it in their searches later, may appreciate to see the final solution to this particular issue.
[Hopefully I will be able to update this thread with a url in the future to show the site in operation, which may help somebody with their project in the future if its set up similarly.]
Alas, it would be nice if future versions of flash had a more direct, flexible, user friendly method for creating navigation.
[We may see development beyond the flash ads which everyone seems to loathe... and more creativity with flash in terms of games, web interactivity, & animation.
Below are 2 sets of code:
a] the first is located within the first frame of the first button, and has some extra variables in it that the additional buttons call upon...

IPhone 4s cover flow slow down and jerky help

Hi all
i have copied my music over from my backup 3GS to iPhone 4s but in cover flow it is very very jerky and not as smooth at all, my 3gs is way smoother an much better than on the iphone 4s it even has problems loading the covers up as there is a delay in doing so as it seems to b slow
whats happend there not as good as my 3GS
So i tried to remove all songs and turned off the iPhone and powered the phone back up and put the music back on and its still jerky and not as smooth what the hells going on this phone should breeze through cover flow view
My 3GS is still on iOS 4 does anyon have the same problems ? Try to scroll fast and it just jerks and slows down but like I say not on the 3gs
Any help

Hi, I have the same problem with my 4s. After reading all the suggestion on this and simmilar forums I checked my picture files assigned to my albums. I selected in iTunes an album, then right click to get pop up menu, selected "get info. Then I went to artwork, copied it (right click, copy), then I copied the picture to picture editor to see the properties. I noticed that some of my pictures assigned to albums are huge, something like 2000 x 2000 pix.
When I repliced them with smaller ones, i.e. max 600 x 600, everything become smoth. Now my cover flow work perfectly as it should be. Definitly ther must be something wrong with iOS5 because before I did not notice such a problem on 3GS of 4 model, even I had the big picture assigned to the album

Why is my new iPad mini with retina very, very jerky and slow?

Hi,
Does anyone know what I can do about my new iPad being very, very jerky and slow?
FACT - The multitouch screen is unresponsive and I have to press and press and press to select what I want before it reacts.
It's an iPad mini with retina, so it's got the new chipset which runs really, really fast.
FACT - What happens is:
I start up pages and it freezes completely for quite a while before allowing me access to my documents.
I go to settings and it freezes up totally for quite a while before allowing me access to my settings.
Is there a cure? I get similar problems on my acompanying really, really fast iPhone 5s.
PS
Plenty of memory left so no problems there - only about half used and they're both 32gb.
...and my beloved iPad2 never used to do this either.

If You Think iOS 7 Feels Slow Here’s How to Speed It Up
http://osxdaily.com/2013/09/23/ios-7-slow-speed-it-up/
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

In "edit" mode, my movie speed is fine. Once published it seems to slow down and become all jerky. Any ideas? Thanks

I have a revision a imac g5 with the same problem with only macbreak podcast. I know leo laporte said that the podcast was done in 1080p and my computer with its built in 64 megabyte graphics card might have trouble with this podcast but your machine must have a better graphics card than mine. 1080p requires at least 128 megabytes of graphics memory built in. My machine played this podcast on quicktime fine until they came out with the update to quicktime last week or two ago. I was going to upgrade my memory until I came accross your story and your machines doing the same thing with much better specs. I think it might be the quicktime update that is causing a problem. Maybe Leo will talk about this problem since he is doing a mac show about macs.

IPhoto in Lion scrolls jerky and too fast

HI all,
since upgrading to Lion, scrolling through events and photos in iphoto has gotten pretty impossible. Using the trackpad on my MacBook I have to scroll extremely slow if i want to see anything at all. Its not actually scolling as much as jumping a few rows up or down. that would be ok (not great, not very "Apple", but acceptable) except for the fact that the speed is so fast I cant adjust fast enough to see where I am.
The visual effect of movement in one direction or another is totally gone, which makes it look like photos and events are jumping all over the place.
Anyone else have this issue?
Thanks!

I uploaded pics to iPhoto for the first time since installing Lion. I am hating it!!
I have the big Mac desktop. I do not understand how to scroll through the photos now. This could be a deal breaker for me. Although, being able to view all my iCal appointments in a glance is awesome.
I am very annoyed right now!

Slowing Down Scrolling Thumbnails

Hello everyone,
I've put together one of those great masked scrolling
thumbnail panels by working through a tutorial. I'd like to slow it
down a bit, could someone suggest how this is done. Here's the
code:
panel.onRollOver = panelOver;
function panelOver() {
this.onEnterFrame = scrollPanel;
delete this.onRollOver;
var b = stroke.getBounds(_root);
function scrollPanel() {
if(_xmouse<b.xMin || _xmouse>b.xMax ||
_ymouse<b.yMin || _ymouse>b.yMax) {
this.onRollOver = panelOver;
delete this.onEnterFrame;
if(panel._y >= 60) {
panel._y = 60;
if(panel._y <= -1000) {
panel._y = -1000;
var xdist = _ymouse - 250;
panel._y += Math.round(-xdist / 7);
Thanks.
Darren.

>>panel._y += Math.round(-xdist / 7);
I'd start here, by dividing by a number greater than 7.

Scrolling is really laggy and slow

For a week or so I've noticed that my scrolling is really slow and laggy on some sites. A site most often visited that makes my scrolling really slow is youtube. Has anyone found a solution to fix this? Was it maybe due to an update?

Hello everyone!
User Hakaitz of the Apple Support Communities has worked out a solution, that has helped me getting my old Mac performance back. It involves installing the graphics drivers from Snow Leopard in Lion.
This performance bug really annoyed me to no ends... Here's what user Hakaitz says in https://discussions.apple.com/thread/3198002?start=45&tstart=0:
There is a fix for this problem.
I just load with kext helper, the Snow Leopard Kexts from version 10.6.2 for the Radeon.
End of stutters on laggy animations on any version of lion. Works on 7.1 and 8.1 imacs (at least).
Here the fix:

How to use ONLY RADEON 2600 USERS:
execute kext helper
drag and drop this files ONLY:
ATIFramebuffer.kext
ATISupport.kext
ATI2600Controller.kext
put your admin password and click on "easy install". I tooks a while to do the work. When finished, reboot (the kext helper aaaaalways hangs, its normal.
After that reboot your computer wont stutter anymore.
Hope it helps!

Since I installed IOS 8.0.2 (was ok on IOS7),on my iPad 4 "photos" don't scroll properly, it freezes and staggers, it's really slow to scroll to the bottom of the page (in Album, Events From My IMac) it's very annoying!

I'm not sure, but I know it's not recommended to upgrade to iOS 8 on anything older than an iPhone 5. I only lost my music playlists and music that was on my phone, but that music is also on my iTunes, not the playlists though, and I don't want to go through ALL my iTunes library to fix it either... But it seems I don't have a choice right now.
Whatever you do, do NOT upgrade to iCloud Drive, keep iCloud till OS X Yosemite comes out, if your computer is a Mac. I also just noticed that all my documents on my phone are gone from Pages, BUT if I go on the iCloud website they are still there. Hopefully it will all work itself out when I can update my macbook pro to OS X Yosemite.
If you backed up your phone and all your purchases off your iPhone prior to trying to upgrade you should be fine... But I'm not even remotely sure.

Solution for Slow Open and Save As Dialogs under 10.4.4

I don't know how many others out there may be experiencing this, but...
I noticed that -- after updating to 10.4.4 -- I started getting really long delays when accessing Open and Save As file dialogs -- I mean, sometimes it would take 5 to 15 seconds for the dialog to appear!
I did a lot of troubleshooting, and finally hit upon the solution a couple of nights ago:
It's the Desktop iDisk!
Going into the .Mac Preference Pane and turning off "iDisk Syncing" has totally eliminated the slowdown.
I think it has something to do with DiskMirrorAgent, since that has frozen on me a couple of times and prevented logoff until I force-quit it.
'Hope this helps.

Hi Matt,
One can always manually mount the iDisk when needed, and it still syncs, albeit in real time, and kind of herky-jerky.
As for the slowdown when multiple items are mounted, I believe I'm describing a different issue, related to DiskMirrorAgent. If and when you get this slowdown (with desktop iDisk syncing enabled), check Activity Monitor, and you'll see DiskMirrrorAgent sucking up most of the CPU time for the time it takes before the dialog appears. My record time was about 25 seconds.
As for slow Open and Save As dialogs when multiple items are mounted: I customarily have several external FireWire drives mounted, and often a couple of CDs and/or DVDs (I produce a radio program, and have several optical drives), and I have had no Open or Save As dialog slowdowns since at least 10.3.x, maybe earlier.
Even when the dialog opens to a directory on a CD that has spun down, the opening time on an Open or Save As dialog is nearly instantaneous for me, suggesting that Mac OS X 10.4.x is doing a good job of caching the data.
But I hear you about the "old days," when it used to take forever to get a dialog to appear, just because a CD was mounted! Maddening!

How do I fix a Safari application that slows down and freezes everything?

Apple called last fall and said my particular Mac had a hard disk problem and they replaced it at the Apple store in late January 2013. I backed up the information on an external harddrive and used Time Machine before to transfer all the information to the new drive. Everything worked well and I finally put on Mountain Lion at 10.8.4. I also have Carbonite as a backup and it apparently was not enabled when I transferred the files until early May. In early May I had not used my iMac for about a month and when I started it I found about 40 named file folders on the Desktop that were empty. Some of those had named items in them but when I clicked on them they would dissappear. The actual files did exist and were not effected when I dumped the apparent alias folders. Safari started and would be ok at first but if I went away for an hour it would slow down. I took it in to the Genius Bar at Apple and they ran some tests and got rid of MacKeeper which they felt was causing the problem. I got my Mac back home and it still started slow but worked well at first and then started going slow. If I opened Word it would also start working at a slower speed. I needed to force quit Safari and the Word progran in order to quit or restart the Mac. I got an appointment for the next day and they ran all sorts of tests and the hard drive was working normally. They tried tweeking different areas and sent me home again. When I started working again it did the same thing, I would start out fine and eventually slow down and needed to be force quit to get out of it. A message came up indicating my MasOSX startup disk had no more space available for applications memory. I took it in a third time and the Genius went to the Activity Monitor and the Safari PID was 221 and %CPU 107, Threads 21 Real Mem 2.73 GB, Virtual Mem 22.00 Kind, Intel (64). I had no idea what that meant. I went home again and it still ran slow and couldn't run the programs for any length of time before it ran slow and affected the other programs so they would only quit if I used Force quit. I took it in for the forth time an they decided to keep it overnight. They ran ASD first to rule out memory. They noticed during the appointment the computer was slow to perform normal tasks such as showing boot options, booting into user, bootingto external user. If the ASD passed then they would perform erase and install and only restore users and application files from backup drive. They did this on Wed and Thur. night and I took it home Friday night, June 14 and it still has the same problem. Typing this message right now means typing and waiting for the words to appear.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; } | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Time Machine very slow, Safari and iTunes have to Force Quit

Anyone else having these issues after Mavericks "upgrade"?
Time Machine is so slow as to be ineffective of useless, symtoms:
     - takes hours to prepare and run a backup of a couple of GB to the Time Capsule, anything up to 20 hrs!
     - constantly revising the amount to be backed up, up and down
     - seems to freeze periodically ad stick part way through with no change to the backed amount for hours, then speeds up, freezes, speeds up
     - time remaining estimate alternates between "casculating, estimates of hours and seconds! wildly inaccurate
              - it's been saying 5 seconds remaining for the last 2 hrs.
     - have done two backup verifications to check for Time Capsule problems - none
     - only two successful backups achieved since the Maverisks "upgrade" due to the time it takes
     - both Time Capsule and Airport Express have the latest firmware and software
Coincident with this, both Safari and iTunes (the latest Mavericks compatible versions) both freeze when trying to quit them - have to force quit. Both experience random slow downs and with the spinning rainbow beachball.
Looks like a Mavericks problem with the Wifi and Timemachine?
Using a late 2008 aluminium unibody Macbook with 8GB of RAM and a 256GB SSD, 100Gb of free space o the SSD. Connecting via Wifi to Time Capsule (2TB, with 1.8TB free) and Airport Express (both n Wifi).

Check whether there is a crash report:
Go to your Applications Folder and open your Utilities Folder. Open the application Console.
In the left-hand column, click on Crash Reporter.
Click on the small triangle under Crash Reporter in the l/h column and they will all be listed.
Scroll down to the latest Safari report and click on it.
Now click on the r/h column (which now only shows THAT crash report and then Command-a to copy it all.
Come back here and Command-v it to post it here!

Flash video in Acrobat X makes scrolling document slow or freeze after playing

I am running an HP Intel Core i7 CPU @2.8 GHz, with 8 GB memory and the 64 bit Windows 7 operating system and using Google Chrome and a Nvidia GeForce GT 220 graphics card that shows:
Total available graphics memory 4095 MB
Dedicated Video Memory: 1024MB
System Video Memory: 0MB
Shared System memory: 3071MB
I made a PDF and inserted a 1 minute flash video into the PDF which has about 3 pages of text.
1. I scroll down to the flash video with no problem...
2. I click on the flash vid and it starts to play, no problem.
3. After it is playing I start to scroll up and down to the other pages and it is fine for a while, but then sometimes the scolling freezes and cannot scroll any more. Also right after the video stops and I try to scroll the scrolling gets stuck. So it hangs for a few seconds but then once the video is stopped I can scroll up and down fine again.
The scrolling limitation appears to be related to the fact the video is playing. But My PC and graphics card are not what I woudl consider 'slow' or out dated.
It seems like quite a bad thing to happen for anyone who reads such a document and plays the video and then decides to start scrolling again to read the text below it.
Leads to a bad user experience...
Does this happen to everyone else out there?
Is there a fix for this?

Rich media (Flash, video, 3D, etc.) is stored in the PDF file in compressed form, and is uncompressed at the point of playback (i.e. when the video activates). This introduces a small delay if you're scrolling past a video, and there's not a lot you can do about it.

Changing the scroll thumbnail size

When I click in the scroll bar, a small thumbail appears (which I call the scroll thumbnail because I don't know what it is actually called). This allows me to scroll up and down, giving me a preview of what is on the page that I will see when I release the click.
Is there any way to make this thumbnail larger?

No. This doesn't work. The moment I release the left mouse button, the thumbnail disappears. I cannot make the thumbnail appear unless the left mouse button is held down.
See attachment: This is the thumbnail I want to make bigger

Scrolling thumbnails.....slow, jerky and pixelate
