Massive delay when switching back to table

Hello,
I have a couple of tabs on my shell, the first and main one containing 2 tables, and the tabs have various elements etc on them. In the last 2 weeks when I switch back to my main tab that has the 2 tables on it there is a massive delay around 8 seconds!
This was never there before, if I have my model empty then the delay is only 1 second, but there is no delay when switching between the other tabs, only when switching back to the one with the tables.
I recreated a static table that was similar, with hardcoded data, even with the 2 tables on that example there was an 800ms, which was noticeable and again no delay on the other tabs when switching.
Anyone have any ideas?
Thanks,
Donnchadh.

Hi,
So I have traced it down to my dropdown box, when my dropdown box list is bound to a node in my model with 650 items it takes about 6.5 seconds, but if it is bound to a node with only 15-20 items then switching back to the table only takes around 1 second.
What is going on here? Is it re-rendering the page?
*update
So added this piece of code to the table
oTable.addDelegate({ onAfterRendering : $.proxy(function(){
console.log('table rendered');
}, oTable)});
It is infact rendering the page twice when switching back to the tab, this happens with the shell and I also tested it with only using a tabstrip and same amount of delay.
Why is this happening? Anyone had a similar issue?

Should iphone 4 receive messages when turned off and display them when switched back on

should iphone 4 receive messages when turned off and display them when switched back on

It's up to the cellular carrier, but I believe most (if not all) will enqueue the messages when your iPhone is off.
So generally speaking, a few minutes after you turn your iPhone on, your messages should display. Similarly, your voicemails would arrive.

How to avoid slide rebuild when switching back to Keynote?

We're doing a presentation in which we occasionally Cmd-Tab switch from Keynote to Safari to demonstrate the features of a Web application. Many of our slides use the nice Keynote builds.
When switching back to Keynote, though, the slide being displayed rebuilds instead of simply appearing as it was when switched away. So if we show a slide that fades in three bullet points over 10 seconds, switch to Safari to show the feature we talked about, and then switch back to go on to the next slide, we have to wait for the entire 10-second build again.
We've tried using Spaces instead of Cmd-Tab to switch to Safari, but Keynote seems to grab on to all of the hotkeys. Ctrl-Option-Arrows and Ctrl-Option-Numbers during Keynote playback don't switch spaces, but change slides instead.
One clunky solution we're considering is adding a static (non-built) copy of each slide where we switch to the demo -- that is, we present over the build, then proceed to the copy before switching away. This might work, but if questions come up and we need to switch to Safari during any other slide with a build, we're still coming back to a repeated build.
Is there an option we've missed that prevents re-building the slide when Keynote "gets focus" again?
Thanks in advance for any help anyone can offer!

I don't think you can go back to the end of a slide with builds - after the builds have finished. So your "clunky" solution, = some kind of similar workaround, may be your only option. I've just worked out another one which might work visually for you, but also "clunky".
The idea is to always go from your slide, wherever you happen to be in your presentation, first to a static slide which looks like a Safari window (made from a screen shot), and from there to real Safari. You can do this easily by adding a hyperlink on all your slides to that one (if you want it on all your slides, put it on the master). When you're done with real Safari you'll come back to the same faux-Safari slide. That's the easy part.
Now, you want to get back to the right place in your presentation. This is more complicated, depending on how many slides you have in all, or at least, slides from which you may want to go demonstrate Safari again. Put hyperlinks on your faux-Safari slide, each one leading to the slide you want to continue from, or even a link to each and every one of your slides. Obviously, this might be unworkable with a huge presentation, but, with a little graphic fiddling, and some presentation practice, it might work.

In iOS 7, apps refresh themselves when switching back to them

I often work with one app and switch to another app, then return to the original. After upgrading to iOS 7, it seems that apps (or web pages in Safari) now sometimes refresh or reload themselves when I switch back to them rather than simply presenting me with what I had before. It's not a behavior I like. For instance, say I'm looking at a photo in my photo app Photo Manager Pro. I switch to another app, then when I come back, Photo Manager Pro seems to reload itself and starts all over at its splash screen, so it takes extra tapping to get back to the picture I was looking at. And Safari sometimes refreshes web pages when you return to Safari from another app.
It seems to happen sometimes but not others, and I can't figture out the pattern.
I don't think this has to do with the "Background App Refresh" feature as none of these auto-refreshing apps are in the apps list under Settings -> General --> Background App Refresh.
Any help in figuring out what's going on?

This is a problem many and probably all are having with iOS7 "Multitasking."
Here is probably the largest and most helpful thread about it, but it doesn't fix anything: https://discussions.apple.com/message/24582055#24582055

Delaying when switching between apple mail and safari

just on mavericks.
it more or less looks and feel ok but...
when I switch between apple mail and safari, everything "freezes" for some seconds (up to 30).
anyone similar experiences?
what could be the cause of that?
its really disturbing.

I am a little puzzled by the libraries and switching between the libraries. My personal computer has the majority of the movies and content that would be transfered to the appletv. I chose to only select a minimal amount of content (of movies and tv shows, music via playlists) so there would be space left that would hold photos. Also, i just want to send over only what I want to view (manual synch) If I switch to my Kids library, it streams all the content well (movies & tv shows)(which is fine and streams well) If I switch back to my library, it shows every movie, every tv show, hundreds of music playlist that I did not choose to see. (stream mode) The only fix is to reboot the computer, and all is well. anyone experience this issue?

Major delay when switching between folders in Mail

More often than not when I switch between folders (inbox-to-trash or junk-to-inbox, etc) none of the messages in that folder show up and it says on top "0 messages".
Sometimes they come back after 5 or 6 seconds. Other times it takes over a minute. There usually aren't that many messages in either the folder I'm coming from or going to.
Any thoughts?

Based on the tons of new messages showed up in the Trash, I suggest the following.
Quit Mail first and using the Finder go to Home > Library > Mail.
Copy the Mail folder and place the copy on the Desktop for backup purposes.
Using the Finder, go to Home > Library > Mail > Envelope Index.
Delete the Envelope Index file and empty the Trash.
The Envelope Index file stores an index of all mailboxes and messages.
Launch Mail and you will be prompted to import mailboxes. Select OK and allow the process to complete. This isn't really importing anything but creating a new Envelope Index file within the Mail folder and re-indexing all mailboxes and messages within.
This may cause more previously deleted messages to re-appear but this should resolve the delay problem.
After confirming all mailboxes are available and there is nothing unusual, you can delete the copy of the Mail folder placed on the Desktop.

[SOLVED] Delay when switching between ttys

When I switch between tt2 - tt6 right after boot, I experience a delay of about 7 seconds
before I am presented with the respective login prompt.
During that time, I only get a blinking cursor in the upper left corner.
Note that I experience the delay for each tty, but only for the first time that I switch.
After that, switching is instantaneous.
It doesn't matter whether I am logged in on tty1 or not.
This problems seems to be relatively new.
Kernel mode setting is enabled.

Okay, I have found the problem.
Seems that I hadn't correctly enabled [email protected].
Journalctl:
systemd[1]: Job sys-subsystem-net-devices-multi-user.device/start timed out.
systemd[1]: Timed out waiting for device sys-subsystem-net-devices-multi-user.device.
systemd[1]: Dependency failed for Automatic wireless network connection using netctl profiles.
This somehow caused the problem.
Whenever I switched ttys before those events, I would get the 7 second delay.
After that, everything was normal.
After correctly configuring netctl, the problem is gone.

Long Delay when switching Flash cast members

I have a movie that uses Flash cast members as sprites. The Flash members are static images and are optimized as best they can be, but they are using Background transpaerent ink and cannot be direct to stage so I know they use a lot rescources. These sprites are rotated randomly, and that is why I must use Flash members since bitmaps look terrible when they are rotated. The user can select to change the sprite's members to display different images. I do this by changing the memberNum property of each sprite.   When that happens on some systems there is a delay of up to 2 seconds while the new Flash cast members are substituted. All Flash members are internal and are set to Preload before Frame 1.
Can anyone think of what may be causing this delay?

Firstly, I'd suggest that rather than rotating the Flash sprite it may be simpler to rotate the contents of the Flash using Flash functions built into the SWF... I'm pretty sure it would be more efficient in terms of processing. If necessary you could wrap your SWF's content into a MoveClip within the main SWF, and then spin the MovieClip using Actionscript in the SWF (if you see what I mean).
As for the delay problem - have you tried using the sprite.member property rather than sprite.memberNum? For example:
on changeMember me, aMemberName
     sprite(me.spriteNum).member = aMemberName
end
I don't know if this would side-step the problem because I've never come across it before, but it's a thought. Bare in mind that memberNum can be ambiguous because it doesn't specify which cast the member is stored in.
Telling members to preload before frame 1 doesn't guarantee that they will be preloaded - you need to be sure that you've allocated enough preLoadRam. The following would allocate 1MB (1024 KB) of RAM for preloading
on startMovie
     the preLoadRAM = 1024
end
If your SWFs are large then you may need to up the preLoadRAM value (assuming you can be sure that your users' systems will have enough free RAM).
Finally, you can use the member.preload property to tell Director whether a SWF must load completely before it plays...:
member("myMember").preload = true
... or whether the SWF can be streamed from disk as it plays...:
member("myMember").preload = false
I hope some of this helps.

Lag/delay when switching between windows/applications in Yosemite

I have installed Yosemite onto a 27" iMac mid 2011 with 16Gb RAM. Since the installation anytime I switch between windows in an application or between applications I get a delay or lag of between 5-10 sec before I can then utilise then next window. I have 3 other iMacs of various ages that I have also installed Yosemite on and there has been no lag/delay issues. One of the other iMacs is exactly the same specification as the one that is displaying the lag/delay. It did not exist in 10.9.5.
Has anyone else encountered this issue?

Run some of the maintenance utilities such as Onyx, Cocktail or Main Menu.
Create a new user account and see if it is also happening there.

Long delays when switching from anything to xterm; Security Update 2008-001

I just updated my computer and rebooted. After it all came up again I opened Safari, selected a url and copied it, clicked on my x-term and it stayed behind my browser! After an excruciating delay of nearly a second, it came up on top. This makes me frequently mark large chunks of text in my xterms by mistake, which of course messes up my cut and paste buffer. I could not believe this so I actually used a stopwatch and it gives me 1.32s between clicking on the xterm until it appears on top.
I can switch just fine between Safari and iTunes, but Safari and xterm gives this behavior. Same with iTunes and xterm. This makes my computer practically useless and I have no idea how to fix it!

Good News!
No OS is perfect, you just get to choose the most important features for you.
PS. Sometimes things do "just work", but we can do little things to increase those odds on our own.

Delay occurs when switching between applications

System worked fine before installing Mavericks. Now each time I switch been applications there is a 5-10 sec delay before the new application responds. The applications don't actually hang, the system does catch up, but it makes the system unusable.
For example, I wil have Outlook 2011 up on one monitor and Safari up on another monitor and each application will work fine and be responsive. But when I click between the two open applications, 5-10 sec delay occurs. During the delay, the first application continues to be responsive (will respond to mouse clicks, can type, can close, can move/resize, etc.) but the second application (the one that I'm clicking to) won't respond to anything. Evenuntaly, the system catches up and the second application becomes responsive, but the same thing occurs when switching back to the original application.
So far, it seems to impact all applications - Office 2011, evernote, safari, webex, adobe reader, system perferences, and finder.
Verified Disk Permissions and vefied disk - no improvement.
Rebooted the system - no improvement.
Ensured spotlight indexing wasn't running.
Any suggestions?

Apple was able to help fix this. From what I understood, they had me delete the Apple settings files and then the operating system would recreate them - sorry, didn't note the specific directories they said to delete. They said it was an issue caused by installing the new OS. Deleting the files fixed the issue.

HT6114 Delaying problem when switching desktop

After upgrading to Mavericks v10.9.2 Update my "Macbook pro Retina, 15-inch, Early 2013" is delaying when switching desktops or switching to mission control. An overall delay problems occured. I need help!

First off, I meant to title this "When switching spaces application window is not showing."
Just in case anyone else runs into this problem or any other weirdness with switching between spaces, the answer seems to be trashing the com.apple.dock.plist file and then restarting the dock. The preferences file can evidentially get corrupted and create some problems. Spaces does not have it's own plist file but stores it's data in the dock's plist file. Be warned that this will reset all of your dock preferences including which apps you have on the dock.

Can you switch back between CS5 and CS5.5 with the same project with Premiere??

Hey all,
I just got CS5.5 for Mac (Lion) and was wondering if i am able to save a project and open it with CS5 Premiere because I work with one other editor who has CS5. I have tested saving a project in CS5.5 and opening it in CS5 but it says that it needs to convert first but then it seems to work fine. So basically, is there workflow good between the 2? Any known issues or anything else i should know about when switching back and forth?
Also, I have the student edition of CS5.5 and was wondering how many times can I install it? I plan on buying a new computer in a few months from now but currently have 2 and was wondering if i should install it on both my current computers and then deactivate one and install it on my new computer in the future? Or is there a limit and that will not work?
Thanks!!

Because it has to create a new "version" of your project every time you go back and forth, you'll end up with umpteen versions if you go back and forth every time which could become a nightmare for you... And because it creates new "versions" every time, you're far more likely to end up with a corrupted file at some point... I'd stay away of going back and forth between versions...
As an aside, does anyone know if you can go back and forth between the same version (CS5.5) on different platforms (Mac/PC)? I may need to start doing that soon at work, and I've never tried...

Lose Dock when switching from External monitor

When I disconnect my external monitor and open my MacBook monitor the Dock is not visible except when I cursor over the Dock area it's starts to reappear? It's very strange.

I think the problem revolves around the change of resolution when switching back. Because my Windows for Safari are out of whack too. So I am thinking the Dock is position wrong at first.

Command Button colors corrupt after switching back and forth from design view.

I would say my experience level with Access is "getting there."
I therefore don't thing I'm making a newbish mistake.
Has anyone else noticed this? As it's bugging me quite badly.
1. A command button has had it's color formatted (pressed, hover, etc. nothing fancy)
2. It works fine.
3. In my navigation form, if I switch to design view, then select a given sub-form... like "customers" - and switch back out of design view, to form view - then without fail, all customized command buttons within that sub forms' color will 'corrupt'
ie, change.
4. Closing and reopening the navigation form (ie, my main menu) restores it, but the same thing will happen should I go back to design view for the sub form.
5. Finally - this behaviour does not happen when switching back and forth between views on the original form that isn't a sub form in the navigation form. (Ie,. the main 'customers' form).
Can any clever folk give me a solution? :(
Thanks,
Eric Rowlands
EDIT - My apologies, I am using Access 2013 for a desktop database.

1) We will need to understand whether the issue is seen on any sample database.
2) IS this seen only on your system, we would need to check on other system also
3) If the issue is seen in all system & issue is not seen in the sample database then this could be database specific issue
4) As per my understanding the issue is consistent, we would need to find what is the VBA code or which code is used while designing this form.
5) We would need to see if the issue is seen only on that particular navigation form?
6) Is the button gets corrupt I mean to say non-usable once it get discolored ?
7) What is your end goal just in case if you are able to work on your database i.e. when working on the navigation form without going in design view is issue still seen there ?
8) Since when are you experiencing this issue ?
9) If possible please provide me the environment details of your system & Access application, whether the issue is seen only in access 2010 can we check in access 2007 or in access 2013.
I would really appreciate if you can answers the above questions this will really help us to isolate the issue further
in terms of technical troubleshooting after answering the above question I might come up with another question so that we can do extensive isolating the issue so the if required we can involve the developer also.
