30EA3: Monitor sessions grid freezes when scrolling lo last session

Hi,
I've found an issue with the Monitor Sessions grid.
Steps to reproduce the problem (scenario I have tested an reproduced the issue)
1. Open monitor sessions window
2. Order the grid by "OS User" column (In this scenario, my "OS user" is the last one alphabetically)
3. Scroll down in the grid, until reach the last record (as mentioned above, the last session is the same session that is monitoring since my user is the last one alphabetically)
Then SQL Developer freezes, processor time and memory start to increase; and also, seems that SQL Developer window is trying to get the focus, so it doesnt let me navigate freely to other applications, is even difficult to open task manager to kill the process since SQL developer window in the background keeps getting the focus of mouse and keyboard.
Thanks and regards
Ramiro Teran

Hi Raghu,
1. As I mentioned, the scenario I tested was the "Monitor Sessions" grid, at first I only tested scrolling down to the last record, in the master grid using the mouse wheel, but now I have also tried crtl+end, and it also happens
2. 184 records in parent grid (Sessions)
3. The child grid is the "Active SQL" tab (first tab) of the detail of the session.
4. Yes, there was a cell in master selected, but when scrolling down and reaching the bottom (or doing ctrl+end), then the last cell is selected automatically, and SQLDeveloper freezes.
As mentioned in my first post, the SQLDeveloper not only freezes, but doesn't let you navigate to other windows (every couple of seconds SQLDeveloper gets focus on its window, even though is frozen)
I have took an screenshot showing the issue, even though, maybe you can't appreciate the issue on an image, since the image only shows the last record of the monitor sessions grid selected, (at that time SQL developer is hanged, and doens't respond to clics or keyboard comands). Also it shows the Task Manager showing increased memory and CPU ussage from the SQL Developer process. If you're interested in this screenshot, let me know where/how to upload it
Thanks and Regards

Remote console session freezes when scrolling

My host: Laptop running Windows XP SP3.
Guest: Windows 2008 R2, physically on a USB hard drive.
My VMware server version is 2.0.2.
I have ongoing problems with the host session freezing up. I have had this problem intermittently while working in MMC on the guest, or consistently in MS Excel 2008 on the guest. Because I can consistently reproduce the problem in Excel, I'll focus on it. The session will freze simply by selecting a cell, and then dragging down to select multiple rows of cells. If I exceed the number of rows visible, the Excel session should scroll down. Instead, the entire session becomes unresponsive. I can not move the mouse pointer or switch or any other applications in the remote session. My only option is to shut down the virtual machine and restart it.
I have also had the same problem when navigating MMC. The entire session will sometimes freeze after I click the plus sign to open up an item. In this case, I have not yet identified under what circumstances the "freezing" occurs.

I am experiencing what I think is the same issue. However, my vmware tools (seem) up to date (declared version is 7.7.6, update option is inactive), and there is no svga driver under c:\program files\common files\vmware\drivers (there is one in c:\program files\vmware\vmwaretools\drivers\video though).
The VM freezes after scrolling up/down in notepad++ , exact conditions are hard to define, but usually after 2 minutes of editing a text file a freeze is guaranteed. Only way to recover is a reboot of the VM (a shutdown never completes). Help appreciated.
Host : Ubuntu 9.10,

Why my Firefox keeps lagging and freezing when scrolling on Facebook?

When scrolling through Facebook it keeps lagging and freezing for a few seconds, and when it happens it says "Connecting..." on the tab title. It keeps happening while I'm scrolling in the Facebook page, and if I leave the tab with Facebook working all Firefox looks a little laggy.
I've tried some possible solutions here in the support but it keeps happening.
It doesn't happen with others browser, such as Chrome.

IPod freezing when scrolling down the music app?

I own a 3rd Generation iPod touch. I plugged it into my computer as usual, but when I decided to disconnect and start listening to the music I had recently put in, I realized that it wouldn't let me scroll very far. I wanted to listen to the Cream albums I had put in my iPod only to realize that I couldn't get past the A's in the list of artists, and if I attempted to go any farther down, it would freeze and crash the music app. My playlists were also wiped blank on my iPod even though they would appear just fine on iTunes when I'd plug in my iPod again.
I've tried resetting and restarting the iPod, closing the music app, and so on, but so far nothing seems to have worked. I don't want to end up having to restore my iPod, because I've a lot of music scattered across different computers and it would be a pain, to say the least, to get that and all the saved photos restored again. Is there anything else I can do?
Thank you,
Clyste

No.

Preview freeze when scrolling

Hi,
When I scroll the pdf in the Preview in Maverick, sometime It will freeze suddenly. And if I move the pointer out of the preview then move it back in, it works.
Does anybody know whats going on about this bug?
Sometimes its anoying.
Thanks.

I found a solution that has worked for me.
I found that under System Preferences -> Accessibility -> Mouse & Trackpad -> Trackpad Options, my "Scrolling" field was set to "without Inertia".
Switching that to "with Inertia" has fixed all my Preview scrolling woes. (I think that is the default setting for a new installation of OS X.) I don't particularly like the intertial scroll, but it clearly works much better than the "without inertia" scroll, which seems to fail in Preview right at the point in the algorithm when the inertial movement would normally be applied to the scrolling pane.

Forms freezes when scroll down datablock

Hi,
I don't know if the following issue should be posted here. If not, please redirect me to the right forum.
When a user scrolls down a datablock (with more than 100 rows), the page freezes and won't respond to any other mouse event. The cursor shows the "busy" symbol. The only thing we can do is to close the applet and the browser. This phenomenon cannot be reproduced. It's arbitrary.
We have oracle application server 10.1.2 with SSL. The datablocks of the forms have the following settings: QUERY_ALL_RECORDS = No, Number of records buffered = 0. The forms are developed under oracle forms 6i and compiled using oracle forms 10g client R2 builder.
We've searched for this known issue and got some results about patches to apply on forms 10g (9.0.4). Are there any similar patches for Oracle forms 10g R2?
If not, how to resolve this freezing issue?
Thanks in advance
Rgds

There was a known issue which caused scrolling to the last record to result in a hang and/or form crash. This issue has been corrected. However, there is no way of actually knowing if this is the same as what you are experiencing. Just because the symptoms of what you describe may be similar to what I described does not necessarily mean the root cause is/was the same.
I would recommend that you are running the latest of all related software. Here are the details related to patches. They should be applied in this order.
1. Patch 10.1.2.3 (released March 2008) Same patch for both iAS and iDS
..... Patch ID 5983622
2. Forms Recommend Patch
..... Patch ID 9282569
3. If you use Jinitiator, the latest version is 1.3.1.30
..... Patch ID 7410076
If you use Sun JRE, the latest is 1.6.0_20 and can be downloaded from here:

Document freezes when scrolling with small black window.

I am using Adobe Acrobat Pro version 9.1 on Microsoft Windows Vista service pack 1.
On many documents downloaded from the web (eg many academic journal articles) a small black rectangle appears in the lower right hand corner of the acrobat window. The rectangle is black, has a red circle with a white cross on the right hand side (looking like a quit button?), and a progress bar, which fills up with a light blue colour, and words below.
The words progress through:
Deskewing Image...
Rotating Image...
Decomposing page...
After which the rectangle disappears. There may be words before or after that are too quick for me to see.
The rectangle appears at the end of a scroll operation, either by dragging with the hand tool, dragging the scroll bar, or even just using the up and down arrow keys. However, it may not happen if the scrolling movement is short. It also occurs immediately after I change any of the preferences.
I have not seen this happen on any documents that I have made myself (by printing to acrobat from Microsoft Word).
I originally had this problem with version 9.0. Upgrading to 9.1 did not fix it.
When a friend views a document that has this problem on my computer using Acrobat 7 the rectangle does not appear at all and the document scrolls normally.
I am guessing that this is something that could be turned off in the settings. I have not been able to find the setting because I do not know what this "feature" is called.
Google searches for terms such as <"deskewing image" "decomposing page"> does not reveal anything, nor did a forum search here for "decomposing"
Any help would be appreciated.
Thanks
Steve

I have the exact same issue, using Adobe Acrobat Pro v 9.0.0,
the difference is it happens for any document, whether I've made it myself or not.
I generate PDFs all the time from CorelDraw X4 and have to open and check them.
The pause whilst it undergoes the messages Steve described is very annoying.
I read online that removing the three "Reader" plugins from the Programme Files folder might help.
I tried that and it did not help.
Below is a screen capture of the problem highlighted in a red outline:

Display ripples when scrolling ANY types of pages

This is driving me nuts. And giving me headaches. And making my head spin.
My MBPro 2.4Ghz with infamous Nvidia 8600M GT 256MB graphics card is the culprit. A real letdown compared to all the Macs in general, and the portables in particular, that I've used over the last 20 years.
As others have reported here, there is a MAJOR issue with "rippling" lines of text when scrolling web pages. But I am getting the same thing when scrolling ALL types of pages: web, text, spreadsheets, etc.
It happens both on the MBPro screen and on an external monitor.
It happens when scrolling with the trackpad or with a USB mouse.
It happens at all times.
And, if this is possible, it seems to be getting worse. It's almost at the point where I have to TAKE MY EYES OFF THE SCREEN if I have to do any scrolling. If not, by the end of the work day, my head is spinning, my eyes are dead tired, I'm going cross-eyed and, more times than not, I've got a headache from all the "visual effects".
I took my MBPro to an Authorized Apple Technician, to see if it had the defective Nvidia graphics card. I'd done a reformat and fresh install of 10.5.7 the night before.
The Nvidia test software, on an external HD, showed that I don't have a defective card.
Not a bid deal in the end, as they would have just installed the SAME type of graphics card and logic board.
I convinced the Apple Tech to use my MBPro for a few minutes, just to show him what I meant. He said he was surprised to see the ripples, that he'd never really focused on that in the past. But they were definitely there, and he wasn't able to say that it was "normal", as he really wanted to do.
He said he thought it might be a problem with the NVIDIA DRIVERS.
He then went onto his 24" iMac with Nvidia graphics card and, lo and behold, he had THE SAME RIPPLING while scrolling longer web and text pages.
This made him more convinced that it must be "imperfect" Nvidia drivers in Mac OS 10.5. And he said the only thing to do was hope that Apple and Nvidia get these drivers perfected and thoroughly tested in the near future, either by specific update or IN SNOW LEOPARD.
What's frustrating is that I have NEVER had this problem with either our iMac 20" Core Duo, which has an ATI graphics card, or our Macbook Core 2 Duo with GMA 950 Intel chipset. That is, with much older, less powerful Intel Macs, but ones that DON'T HAVE NVIDIA graphics cards.

I call it more of a flicker, but I also experience this issue with a MBP (led backlight). It is not browser dependant, but as Safari scrolls smoothly, it is much more apparent with this than other browsers.
Here is a perfect example, watch the sidebars on this page while scrolling :
http://www.theautochannel.com
It's also particularly bad with this site (apple discussion board), and others with high contrast text, the text flickers/ripples very badly This never happened with my Powerbook display. Is this an issue or simply inherent with these displays. Personally, it is giving me headaches when scrolling through large amounts of text (which I often do for work), and rendering this laptop virtually unusable for me.
I'm surprised to find very few others complaining about this phenomenon, perhaps I'm not describing the issue well with my search terms. Has anyone heard of a solution?
Thanks

Imac pointer freezes when installing OSX,

Imac intel 2010, mac freezes when Scrolling (Safari, Adobe PDFreader. called support, they suggested a hardwaretest, done that result OK.
Than they suggest to clean HD and to instal OSX.6 again.
Deleted HD. Try to do new installiation OSX6 from dvd, Imac freezes again during installation for several times at ca. 32 minutes to go.
What can i do?

You can attempt to reset the PRAM in the machine, but it looks as though there's a hardware problem. It's actually kind of difficult to determine if it's the graphics hardware or the mainboard, but neither are really servicable. You'll want to take it to get serviced.

All windows/tabs aren't opening from last session, even with setting checked. What's wrong?

For a while now in Safari, if I have to close out the browser or restart my Mac for some reason, my previous tabs in Safari are not loading when I re-open Safari. I went online this week and did a change in Settings to where it would open up the option again in Safari to allow me to check "Reopen windows from last session", however, even with this selected, it did not re-open my tabs just now. This is such an unnecessary frustration and hassle. Can anyone please help?
Oh, and the "Reopen last closed session" and "Reopen all windows from last session" is grayed out and unelectable if I try to bring them back that way in History.

Thank you Linc! I did do what you suggested, and it did work.
I noticed though (because I tried to close/re-open Safari several times to make sure it would consistently load my previous pages, that when I close the window but not the program) that I can "restore my previous session" or "last closed session" under the History menu if I merely close the window, but not the app/program although it doesn't automatically reload them; but, if I close the whole Safari app/program, when I re-open Safari it does reload all of my pages. I guess I'm writing that in case it helps someone else, but it can be confusing, and may be where my issue originally started.
Okay, another thing is, when I look in Safari preferences now (after your suggested changes), Safari doesn't give me the option of "Open new windows with previous session". Does that matter, I guess, if my previous pages/session are/is loading? It doesn't seem to make sense that that preference is missing in Safari now, but my pages reload. Just some musings. No rush to reply. I'm new to Mac, but I do like to understand how things work.
Thanks again!

Firefox freezes when opened on secondary monitor using default profile. Other profile okay.

Windows 7. Firefox 28.0. Hardware acceleration is off in both profiles.
Default profile behaves normally in the primary monitor (I have two monitors). When I open the default in the secondary monitor, it appears to be at maximize size but only the top bar of the screen is visible. If I shrink it, it locks up, but I can slide it over to the primary monitor where it then works normally.
If I open it in the primary monitor then move it to the secondary, it shows in a less than full screen. When I maximize it, a duplicate screen partially opens and both freeze, and menus freeze when I open them. I can slide it back to the primary where it works normally.
My other profile is an old one with all the bookmarks, settings and history. It works fine on both monitors.

Freezes when I open it...or when it idles, or when I try to scroll, just always freezes since latest upgrade

It freezes all the time. I cant use it anymore. When it freezes, it freezes my whole computer. Can't ctrl, alt, del to get it to quit. Nothing works...cant exit...nothing. The only thing I can do is power off with the power button.
It freezes on all moves...switching to email, adding a tab...sometimes when scrolling on a basic website....sometimes it will freeze while idling. I tried uninstalling everything...and reinstalling. I tried making that folder a .old folder (forgot what it was called) It was in the support section. Ive tried everything in support but it still freezes Tried running without add ons etc. Nothing works. Safe Mode wont work either. I have a fairlynew computer with very little loaded so I know it's not my system....plus it worpked fine before it loaded latest version.

How to re-create your iTunes library and playlists
Rebuilding an iTunes Library: How to Do It & What to Expect

Since upgrade to FF13: having problems with flash content, especially videos when scrolling/multi tasking--freezing the video and sound for 1-2 sec. Any advice?

At first, the same night I decided to update--things were fine but after using the browser hours later a second time: some flash scripts would simply not respond and freeze the tab the content is on or like in my question, constantly stutter. The problem for flash videos only seem to occur when I scroll onto links or when moving up/down a page. I encountered similar problem with FF7--like that time, I installed/uninstalled the flash player and even resetted firefox but to no avail--the problem persisted. It is also present while in safe mode. P.s. such problem is seemingly not present in other browsers which brought me to ask this question for assistance.

I have the same issue. When I scroll past embedded videos, such as YouTube videos, they are torn or disrupted. The video may shrink in size when I scroll, etc. Issues only arise when scrolling past the video. When playing, no issues.
I've tried the following that did not help:
Safe mode
Video driver up to date
Flash completely up to date
All plugins up to date.
Only started happening when I updated to FF13.

After installing Snow Leopard on MacPro with 23" HD monitor I have noticed an anomaly when scrolling up or down, a horizontal ripple appears briefly, I have tested other browsers and there is no problem, only in FF 8. What is causing this?

Hi applecore_eater,
When Leopard came out, machines were shipping with Tiger for 3-5 months after it's release. So the fact that you bought a machine with Leopard still installed is not uncommon, especially considering we're not even a month into release. Matter of fact, I'd be surprised to see a lot of machines (unless CTO) that are coming with Snow Leopard.
The battery issue is not specific to Snow Leopard or the MacBook Air. I've deployed SL to about 15-20 MacBook Airs and all of them have been perfectly fine (batteries).
