Frontmost app's Main window loses focus randomly

Sep 1 12:04:52 retina.local WindowServer[91]: CGXSetWindowListAlpha: Invalid window 0
Sep 1 12:04:53 retina.local Dock[35334]: CGSReleaseWindowList: called with 12 invalid window(s)
I keep seeing these in the logs when it happens. It is obnoxious to be in an app and then hear the error noise because the app I am currently working in loses focus for the window I was working with. For example in Mail, I can be working and the window will lose focus so keyboard shortcuts stop working.

I am having the same problem, and here is what I have figured out so far;
I installed a stopwatch application so I can time it, and it is happening exactly every 5 minutes. Moving the mouse, changing the foremost app, activating the screensaver, or anything else I have tried doesn't interrupt the timer. It will still happen exactly every 5 minutes.
I am currently looking in the console logs trying to find anything that is going off every 5 minutes.
It happens even while typing suddenly I will get beeping because the top window I am typing on loses focus. The application name in the menu bar does remain the same as the current application, so another application doesn't seem to be coming forward, just the top window goes inactive.
If anyone else is working on this issue and wants to see if their problem is exactly 5 minutes also, you can install the stopwatch application here; http://www.macupdate.com/app/mac/42353/timi
I will update here is I figure out which application is causing this problem.
The answer shouldn't be "reinstall your OS" for every little problem as Apple always says.
Hopefully we can figure this out without having to resort to such a drastic measure.

Firefox 3.6.8 does not recognize subsequent mouseclicks - window loses focus

After updating to firefox 3.6.8 on my macbook pro (OS X 10.4.11) Firefox fails to recognize subsequent mouse clicks. You can access the page initially, but then it seems to lose focus and become unresponsive to mouse clicks until you do something to break the cycle (clicking on desktop, minimizing and resizing window, etc). I reinstalled Adobe Flash update using full installer, since others have suggested that as a possible cause, but no joy. The browser window still does not recognize mouseclicks after an initially successful page load. You can tab to the next window (for example, if you want to enter something in search) but you cannot CLICK to enter the search window, nor can you click on links on the page, etc. It is totally unresponsive.
== This happened ==
Every time Firefox opened
== I updated Firefox to the version just before 3.6.8 -- then I updated to 3.6.8 to see if that fixed it -- it's still broken

This started happening to me yesterday. All plugins are disabled, didn't help. All plugins uninstalled, didn't help. Downgraded to SP3, didn't help. I've also noticed this happen in Thunderbird, though it seems OK now.
Sadly I've had to start using IE8 :(

Using web.show_document the first time makes new browser window lose focus

Hi,
In our application we use show_document(url, '_blank') to open our reports (as pdf) in a new window.
Our environment is Application Server 10g Release 2 with Forms 10g Release 2 and jinitiator 1.3.1.22.
The first time I call a report, the new browser window containing the pdf is shown but loses focus after about 1 second. The focus is then returned to the applet window. When calling a report again it always keeps the focus.
After closing the applet window and restarting the application, the same thing happens: first report called loses focus, all others keep the focus.
Does anyone have any idea why this is happening? We want the focus to stay on the new browser window every time...

Hi Jeroen,
I m also facing a problem something similar to yours. If you got any solution please let me know.
Problem-
Currently my application is running on Forms 9.0.4.2 and my form calls another third party which displays the image in image viewer in new browser. When user clicks on the button to display image, then I m using the following Code -
-- Method: displayDocuments ([Ljava/lang/String;)Ljava/lang/String;
FUNCTION displayDocuments(
obj ORA_JAVA.JOBJECT,
a0 ORA_JAVA.JARRAY) RETURN VARCHAR2 IS
BEGIN
args := JNI.CREATE_ARG_LIST(1);
JNI.ADD_OBJECT_ARG(args, a0, '[Ljava/lang/String;');
RETURN JNI.CALL_STRING_METHOD(FALSE, obj, 'com/hli/imaging/adapter/LK_FormsImagingAdapter', 'displayDocuments', '([Ljava/lang/String;)Ljava/lang/String;', args);
END;
Image is displaying fine but the focus is staying on the newly opened browser. I want it to get back the focus to the forms window.Is this possible ???
Thanks in advance

Second window loses focus

Hi all,
I set up a navigation between two wd applications within the portal. The navigation will open a new window once the user clicks a button in the first application. The navigation itself works well, however, the new window is always shown behind the portal page, in other words, it loses focus after it is opened.
Does anyone know a way to bring the new window to the front?
Thanks!

hello thomas!
is this problem with the losing focus when you open a second window fixed now?
can i set the focus in a new opening window manually?
thanks for your help...

When does a selection in a text field in a Finder window lose focus?

Hello,
this problem has emerged on account of an Applescript file that needs to access a text selection (portion of a filename highlighted) in an open Finder window.
The bare minimum code to demonstrate the problem is this:
*tell application "System Events"*
* *tell process "Finder"*
* *set selText to value of attribute "AXSelectedText" of text field 1*
* *end tell*
*end tell*
other variants also exist, using "keystroke" but that does not work either. I am not asking help with Applescript here, it is here only to give a sense of the problem.
My conclusion thus far is that the selection lose focus before the script process can access it. In the best case I get the full filename by using "attribute" and copy of the alias onto the clipboard by using "keystroke".
So my problem is this:
It seems that the focus stays alive when one clicks on a menubar item, any click on any other item on the desktop, including windows of irrelevant applications, changes the focus from the selection within the text field corresponding to a filename, to the filename itself.
And my question is this:
Is there a changeable setting within the OS that has to do with how long the focus stays alive on a selection within a text field corresponding to a filename? If yes, how do I change it?
Thanks

baltwo wrote:
Thanks for clarifying. Never heard it called a text field, just a label. So, exactly what are you trying to accomplish? Is it that you want AS to select the file, highlight its label so you can edit/change it with some other text? If so, have you checked out the Finder scripts installed on the machine, especially the Finder script *Add to Finder Names*?
UI Element Inspector calls the activated/editable filename a text field.
Actually I want to modify one of the stock Finder scripts. I want to be able to select part of the file name in the active text field of the Finder window, then activate the script, *have the script pick up the selection* as a text string then use it internally.
The bolded step is the one in question.
Every attempt fails on the fact that the focus is lost from the "text field" and it reverts to the label for the filename, if I may use this distinction, (or to "FinderItem" in the parlance of UIEI) as soon as another process begins, it seems. So when the script becomes active, but before any of the commands is executed, the selection disappears.
My guess is that it is not some absolute necessity but a setting that perhaps can be changed somehow.

Making JFrame Window Lose Focus to a Native Window

How can i from within the same JFrame code or another class with the JFrame reference make JFrame lose focus to another native window on the desktop.
Any tips

In the core java API you can not make a native window take focus, you would have to use native code (JNI).
The best you could do would be minimize the JFrame.

PP CC & AE CC: Windows lose focus, AE stops playing RAM preview

I'm experiencing very odd behavior when I have Premiere Pro CC and After Effects CC open at the same time. Please let me know if there is any additional information I can provide to troubleshoot this issue.
Symptoms:
I'm working in Premiere Pro CC and After Effects CC and am noticing some very odd behavior where I'll be working in an application (any Windows application) and the Window will lose focus. For example, as I'm typing this question, the window will periodically lose focus, and I'll have to wait a second to start typing again.
Another Symptom is that I'll be in After Effects CC, I'll press 0 to do a RAM Preview, but AE will stop looping for some unknown reason. It's never at the same time and it's always intermittent.
Obervations:
This only happens when I have both After Effects CC and Premiere Pro CC open at the same time
With Sysinternals Process Explorer Open, I notice that CEPServiceManager.exe (Adobe CEP Service Manager) opens as a child process of Adobe Premiere Pro.exe. When this process is open, I experience the symptoms described above. When this process stops, the symptoms stop.
I think there's only an issue when the PP CC project has a linked AE comp in it.
Steps to Reproduce:
Windows 7 Utlimate x64 SP1.
Open Premiere Pro CC and Create a new Project
Open After Effects CC and create a new comp.
Save the Project in AE CC.
Add a solid to the comp.
Save the comp.
Drag the AE Comp to the PP CC project.
Make a change to the AE Comp.
Expected:
Windows behaves normally. After Effects behaves normally.
Actual:
Symptoms occur as described above.

That is to be expected (unless you have a RAID setup for your computer's hard drives). An uncompressed HD file has a data rate that is much too high for your hard drive to handle. If you take that high data rate file into the Adobe Media Encoder and render it into a deliverable format such as H.264, it should play back without issue. If this is the case (and I'm pretty sure it is), this is unrelated to your RAM preview issue.
What version of AE are you running? You say CC, but is it 12.2.0 or 12.1.0? If you haven't yet, update to the latest version; it fixes a lot of bugs.
Also, when you say you've been using AE version 5 and 5.5, do you mean CS5 (actually version 10) and CS5.5 (actually version 10.5) or do you really mean you're using the really old versions?
harcnowhear wrote:
We have an older mac here which has an older card with more ram (1024 MB) on the card, which takes longer to render the preview (is that due to less system RAM?)
Rendering speed usually has less to do with RAM and much more to do with the processor's clock speed. This is likely the difference.
Is this older Mac running CC or is this the older version you mentioned in the "Extra notes" section?
Have you tried updating the driver for the graphics card? The GPU has very little to do with rendering in AE (except for the Ray-Traced renderer, but that doesn't matter as you don't have an NVIDIA card), but it does have to do with AE's display of its playback.

Window Loses Focus After Modal Dialog is Dismissed

hi,
I need a JDialog to be opened when i click on a button in JFrame.and it should be modal so that user must not get control to its parent window and rest of the windows can be accessed.
So, i tried setting property like setModalityType(Dialog.ModalityType.DOCUMENT_MODAL), but still unable to access all the windows not only its parent until the dialog gets closed.
Another issue i was facing is when i close out the dialog i need to get the parent to Front of other windows in application. But in my case it was not happening.After closing the dialog, i am getting the last focussed window to front but not its parent. I tried calling getParent().toFront() in windowClosing() Listener of that dialog, But still not able to solve the problem.
Hope someone understands my problems and give me solution.
Hoping for quick response and thanks in advance.

Then the second dialog's modality will not impinge on the visibility of the original parent window. For instance:

[SOLVED] stay fullscreen in flash videos when window loses focus

I am using the awesome window manager, and am trying to view web videos (youtube, vimeo, various other flash players) in full screen on one monitor while doing something else on another monitor. I have seen people post issues with flash and other web-embedded videos and awesome, but those tend to relate to the videos getting tiled or being full screen behind the browser window or something like that. I am able to get fullscreen to work just fine, except when i transfer focus to another window, it pops out of full screen. Anyone have any ideas for keeping full screen even while the window doesnt have focus? Thanks!

Figured it out. I tried doing the same in Gnome, which had the same problem. Searching for linux more in general lead me to http://www.buttonhome.org/articles/23-l … itor-linux where they suggested going into libflashplugin.so and manually changing _NET_ACTIVE_WINDOW to something like __ET_ACTIVE_WINDOW, which did the trick.

Playback pauses when the window loses focus. Can I fix that?

When going through footage, I might be multitasking -- talking on chat, looking at to do lists, etc. Whenever I tab away to some other application, playback pauses in Adobe Premiere Elements 13. This is really annoying -- any way to turn that off?

JustinPierce
Your type of situation has been written about before and remains the same up to and including the current version 13.
What you describe is what it is. There is no way to change that behavior. The Premiere Elements playback in progress stops when you
switch to another application. No user turn off switch to prevent this from happening.

Gnome 2.28 - separate X server, apps lose focus?

This is quite hard to quantify, but since updating to gnome 2.28 (with the appropriate GTK updates, of course), my apps seem to be losing focus randomly.
This is easiest to notice in Nautilus because I tend to use the buttons (back, up level) most often. When I first start nautilus in the second X server, all the buttons show as clickable (box around them when I mouse-over) and work, but once I start browsing by clicking on folders in the main pane, a mouse-over of the buttons doesn't show them clickable, and clicking on the buttons does nothing. This can be fixed (sometimes) by alt-tab and going back to the same window, or (all the time) by clicking the drop-down arrow for history (back). When this happens, scrolling the mouse won't scroll the folder in the pane, though I can use the keyboard to page up and page down.
Similarly, in my Eclipse IDE clicking some buttons will disable all buttons, which will still be accessible through their keyboard shortcuts but not by clicking on them (no response, as if an invisible app was on a layer above them).
Have no idea where to begin searching for information about this, no error logs (not that I'd expect them), just weird behaviour. Does this happen for anyone else?

http://bbs.archlinux.org/viewtopic.php?id=82894 also mentions it.
Am surprised this affects nautilus, though...

Problems with titler window losing focus

I'm using PP2.0, running on windows XP x64. It's been running since it was last re-installed in December 2007 (after a problem with codecs that broke PP2), and I've made no changes to it or to any of the support processes it uses, nor any changes to the OS (apart from service packs). There have been NO driver changes, window layout changes, workspace changes, or any other changes (apart from entropy). The mouse I'm using is a [oxymoron]Kensington Expert Mouse Pro[/oxymoron], with their latest (i.e. 2007) drivers, and XMouse ver 1.37.0.0 (i.e. their latest x64 driver), but this happens regardless of the mouse or keyboard I use.
To set the scene... I use a "standard" title template for all my video work, with predefined text fields and colours and so on. There's nothing bizarre or extraordinary about these templates, they're actually super simplistic in terms of what most users here use their titlers for! The entire title is completely static - there are no scrolling or moving anythings, the title is overlaid on black video, there are just a dozen simple text boxes and one standard logo (bmp format), that's it. I use only Arial fonts, with no special settings or kerning or spacing or anything more complex than colour. I haven't touched or modified the original titler template since I set it up in December 2008. The problem I'm seeing happens to any titles, not just the known working template, so it's definitely a PP2 problem, not a titler problem.
The problem is that recently (in the past 3-4 months, over maybe 5 projects in that time) the titler window loses focus while I'm using it, and the PP2 main application becomes active.
When I bring the titler window up (using any method) and start editing, that window loses focus (window frame reverts to the background windowframe colour) and I can't type or do anything else in the titler window.The PP2 app window suddenly become the active window, and remains active until I shut down the titler.
My workaround is to click and hold in the titler window, on or around the text I want to edit. So by pressing and holding the left mouse button, I can insert text just fine in any existing text frame. And by selecting text with the left button and then holding it (like I'm starting a drag operation), I can _replace_ the selected text - but as soon as I release the mouse button, the focus leaves the titler and I can't do anything again.
I've reset the workspace, changed mouse and keyboards, but the problem isn't a hardware or driver issue. PP2 is the only application that behaves like this, and it's the only Adobe application that behaves like this - Photoshop (5.5 and CS8) and Audition (1.5 and 3.0) all work perfectly normally.
This behaviour occurs with titles I've used and saved in previous working projects, it happens with new blank titles, and so on.
What I've noticed most recently while trying to fix the problem, is that sometimes I can actually type a couple of letters or hit an editing key or two in the titler window normally, but then the titler loses focus and keeps it lost permanently after that. That doesn't always happen, and it doesn't appear to be related to process flow. So restarting PP2, or closing and reloading a project, don't affect the arbitrary nature of the "sometimes starts to work" behaviour. I can sometimes re-edit a title in the same project after editing the title with the focus lost, and suddenly the first few keystrokes are normal, but then the focus reverts to the main app.
If anyone has any ideas or suggestions to try (apart from reinstalling the application again or upgrading), I'd be most grateful.
-PCPete

I think you're right, it's starting to look like another problem within the "new" PP2 installation. It's such a complex app, it's not surprising it gets lost.
Since this is the only app that has this problem (and because of the nature of the problem), I know it's not a graphics card or driver issue.
This appears to be a high-level windows function problem, to do with the way the PP2 app is handling the modal form. It's probably not the mouse driver, since I don't move the mouse outside of the child window, but that doesn't leave much else. I don't have popups or any other asynchronous applications (like email warning windows or balloon-type reminders or notifications) either.
I really don't want to go through the horror of yet another reinstall of an Adobe product if I can possibly avoid it, but pending no other useful ideas, that is an absolute last resort.

When I open a separate window and start private browsing my main window closes and I lose all of my app tabs

whenever I open a new window and do private browsing it closes my main window and I loose all of my app tabs. If this is functioning as designed then it is a flaw in the design.

It is designed that way. When you stop private browsing, all of your other tabs will come back.

Is there a way to keep the ADL open when testing CS5.5 Air apps after it loses focus?

When I test Air applications (specifically targeting mobile) it seems that when the ADL (Air Debug Launcher) launches, it will automatically terminate the session when I click on anything else other than the ADL window. I have been trying to use 3rd party application debuggers that provide improved memory diagnostics, but these debuggers only seem to be able to work when the application is launched through the Flash Player and not through the ADL. Unfortunately, the Air specific code will only work in the ADL. Is there some way to keep the ADL running even when it loses focus? I have tried using the ADL from the Flash CS5.5 IDE as well as from the command line and both will terminate upon losing focus.

- Transfer the app to the computer by:
iTunes Store: Transferring purchases from your iPhone, iPad, or iPod to a computer
- Connect the iPod to the computer and make a backup by right-clicking on the iPod under Devices in iTunes and selecting Back Up.
- Restore the iPod from that backup. That should also update the iPod.

Preview and TextEdit windows continuously lose focus

Preview and TextEdit windows keep losing focus.
In other words, I select the window, but them moments later it deselects itself (title and traffic light buttons grey out).
The app's menu is still visible (ie it still appears as if Preview or TextEdit is the active app).
But if I do single-app-expose, no windows appear at all and I just see a blank screen (ie as if the app doesn't have any windows open at all).
So it's almost as if the app isn't aware it even has windows open?
Anyone else have this? Any ideas for a fix?

I'm not sure of the name or if it is even accessable from system monitor. I had the same issue with the daemon relanching the app and ended up uninstalling everything until there is a fix. I believe the last update is from 2009 so it's not in active development and chances of an expedited fix aren't great. I wrote an email to axiotron the same day as my oruginal post here and have not received a response yet.
While a complete uninstall is more of a trade off than a solution it may be the only 'fix' for the time being. To uninstall you may need to run an app from within the installation dvd or disk image.
I'm not near my mac right now but will double check some things in a bit and post if I discover anything new and useful. In the mean time you can check for options within your app that may disablethe autostart feature. This doesn't exist in Quickscripts so I was forced to either uninstall or deal with the bug and not use textedit and preview.....I chose to uninstall of course.
