Quicktime "runs" but no window.

When i invoke quicktime (pro) a window blinks on the screen, then nothing.
It's visible in the taskbar and i can close it.
Reinstalling didn't help.

Thank you so much, b noir, for pointing me in the right direction!
iTunes came up ok (i never use it, don't know how it got installed).
After googling "Qoologic adware" i became aware of CCleaner.
Actions Taken:
1. Uninstalled iTunes. (perhaps irrelevant).
2. Downloaded and ran CCleaner.
All is now OK!
p.s. i have just started to use Quicktime Pro, and am makeing movies from image sequences. Before the problem occurred i posted my first one to Youtube, title "RAINBOWORLD 22.5", and based on your thumbnail image, i think you might like to view it.

After updating to Firefox 11.0 Mac, Firefox runs, but no window can be seen

I'm running OSX 10.5.2 I just upgraded to Firefox 11.0. Firefox runs, but no windows can be seen.

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
*Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
In Firefox 4 and later Safe mode disables extensions and disables hardware acceleration.

I tried installing an update to QuickTime. An error occurred and it wouldn't install. I tried removing the QuickTime program, but a window appeared telling me that a fatal error ccurred during installation and I could not remove the program. Now what?

I tried removing the QuickTime program, but a window appeared telling me that a fatal error ccurred during installation and I could not remove the program.
I think we'd better see if some other application (other than QuickTime itself) has dropped old QuickTime componentry in the system files on the PC. (If there's a version mismatch between the old componentry and the "QuickTime proper" componentry, that can create those symptoms.)
So we'll go looking for the older QuickTime componentry in the most common locations for it to be stashed.
First we'll need to change some view options on the PC.
1. Open My Computer from the desktop or Start menu.
2. In the Tools menu, click Folder Options.
3. Click the View tab.
4. In the "Advanced settings" pane under "Hidden files and folders" make sure that the "Show hidden files and folders" option is selected, and the "Hide extensions for known file types" option is unchecked.
5. Click OK.
Now in My Computer, open your C drive.
Open the "Windows" folder.
Open the "system32" folder.
What files and/or folders can you see in there with QuickTime in the file/folder name? (In a standard installation of QuickTime, you should see precisely two files ... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)

OSX: FF running, but no windows open - clicking on the dock icon should open a new window.

Running OSX 10.5.8, FF3.6.10. If I close all FF windows, but leave FF running, I should be able to open a new FF window by clicking the dock icon. This doesn't work - it just brings FF to the front, but no windows open. Any ideas how I can fix this?

Is an external display connected and turned off? If not, open Mission Control. Do you see the window(s) in any other spaces?

Firefox process running, but no window?

Firefox crashed while I was away from my
computer (Windows XP, FF 7.0.1). Re-starting
caused the firefox.exe process to appear in the
task manager, along with 7 plugin-container.exe
processes, but no Firefox window appeared.
Re-booting and re-starting FF gave the same
result. Then, after several minutes, while
reporting this bug via IE, suddenly the FF
window appeared, and restored the tabs that had
been up when it crashed.

Firefox will not open. Process runs, but browser window will not open.

I am unable to get the Firefox browser window to launch. The application will attempt to open, but the browser window will not appear. Task manager indicates that the process is running, it just will not launch the window. No amount of restarts or reboots will make a difference. The strange thing about this is that Firefox has never run. This is a new computer and this issue has been a problem since it was first plugged in.
Troubleshooting steps attempted thus far:
1) Attempted to open in safe mode - will not open
2) Attempted to run in administrator mode- will not open
3) Completely uninstalled application, including profile info and reinstalled
4) Uninstalled known conflicts - Skype 4 (do not have Norton)
5) Even though issues since new, I ran a virus scan just in case-nothing
6) Uninstalled Chrome which I installed after originally being unsuccesful at getting FF to install (I uninstalled it before I began all of these troubleshooting steps as I have heard of conflicts)
I am now at a loss and willing to try any other steps that you guys can suggest.
Computer is running Windows 7 pro 64 bit. Running McAffee virus software. There are three identical computers in my office, purchased at exactly the same time with the same configuration. Mine is the only one that will not run firefox. Sadness. Please help, pleeeease...

Win 7 with iTunes installed - I was also having problems with that.
"netsh winsock reset" at the command prompt resolved all issues and Firefox launched normally.
Check to see if Winsock is corrupted. May prevent FF from communicating with the web and consequently fails to launch properly - for my situation was not a firewall or antivirus block!
http://support.microsoft.com/kb/936211#LetMeFixItMyselfAlways
Click Start, and in Start Search, type cmd.
Right-click the cmd entry that appears in the search results, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
At the command prompt, type the following, and then press ENTER:
netsh winsock reset
Then, you should see the following message:
Successfully reset the Winsock Catalog. You must restart the computer in order to complete the reset.
Restart the computer.
Note If you receive an “Access Denied” error message instead of the message that is mentioned in step 3, the command prompt was not correctly elevated. In this case, close the Command Prompt window, and repeat steps 1 through 3. Make sure that you correctly implement step 2.

TS4123 When I run autoruns as suggested by TS4123, a DOS program runs but no Windows box opens, so I can't check for LSP conflicts

I am trying to troubleshoot an iTunes problem, which may be related to the resources issue that has been previously identified.
My problem is that once iTunes has been running for more than half a day or so, when I play music the program "skips" through the song, playing snippets a fraction of a second long. A 4 minute song will be done in a few seconds. The program then skips to the next song and this repeats. Rebooting solves the problems for a few hours, then it reoccurs. Other symptoms include iTunes not responding quickly, especially to closing it.
As per TS4123, I tried to rune the Autoruns program to see if I had a conflict. I launched the program and a DOS box opens and runs some command line items, but nothing else happens. I don't see a Windows box like I should.
Help on either problem?
I am running Win4, 64bit, on an HP desktop. I have updated video and audio drivers.

You should run the windows based file AUTORUNS.exe instead.

Firefox is running, but no windows/tabs are showing - what gives?

Firefox12, iMac i5, Snow Leopard 10.6.8, 16GB RAM, 2TB drive.
Firefox worked fine this morning. This afternoon, when it fires up, no windows/tabs show up ... just the menu.
I know that the windows are working - a video link that I clicked on in my Mail begins playing. I can hear it. Just can't see anything.
I've tried opening a new window - nothing happens. I've tried restarting after turning off all Add-ins. Same result.
Tried opening the FF prefs but nothing shows up. All I can see is the FF menu - nothing else shows up.
I've tried the History menu - to restore all tabs etc etc ... no difference. I can only see the menu.
This is so weird and I have no idea what to do.
Any suggestions/ideas??

That is weird. Do you maybe have a window minimized to the dock or in another space? Have you tried restarting the whole computer?

I can open the program and see it's running, but the window is invisible or too small to see.

I've tried scanning the help forums and was told that it's probably a corrupted file that saves my preferences upon closing, but all in the info I can find about this is for earlier releases.
I've tried clearing caches, opening images that might force the window larger, uninstalling and reinstalling, and restarting my computer. Suggestions?

You can use Save & Quit with one of these Startup settings:
* Tools > Options > General > Startup: "When Firefox Starts": "Show my home page" or "Show a blank page"
Save and Quit will only work if you close Firefox via "File > Quit" to close all open Firefox windows. 
If you use [[Clear Recent History]] to clear the 'Browsing History' when you close Firefox then restoring tabs from the last session ("Save & Quit" or "Show my windows and tabs from last time") doesn't work.
You can reset the warn prefs on the about:config page via the right-click context menu.
* browser.tabs.warnOnClose , see http://kb.mozillazine.org/About%3Aconfig_entries
* browser.warnOnQuit , see http://kb.mozillazine.org/browser.warnOnQuit

I tunes doesnt work since new update. shows in processes but no window displays.

Running windows 7 premium(it is a legit copy). it seems to me that every itunes update that i do,seems to make itunes NOT work on my computer. the only way for me to get it to work is to litterally reboot windows 7 on to my computer....ive dont this 4 times in the last 6 to 12 months. have to reset my computer completly just to get one file to work. im not doing that this time. i know its not my computer cuz everything runs perfect on my cpu but itunes. i dont care what update it is, this has always been my issue for as long as i can remember . i will click to run as administrator, i tried to netsh ....blah blah reset. i update my computer to all the new updates. i downloaded quicktime i did everything i can find on this support page as possible. im just getting tired of this. my computer will show as if its opening itunes and nothing comes up. ill sart task manager go to process and it shows as if itunes is running. but no window will show. to make things even more frustrating maybe 1 out 10 tries..literally 1 in 10 trys itunes will appear....after i have given up and just do my own thing itunes appears after an hour or so but just freezes. ... any one else having trouble like this or has solved this problem?
im tired of spending 2 hours to reboot my system and have to get my computer reset and another 2 hours to update and put all my files back on and even if i get itunes t owork i hate sitting here for another hour putting all my music in ths system and another hour for it to be uploaded to my ipod.....
itunes do your self a favor have your people that work on all itune updates, all so fine tune the windows version update!

i think i figured it out.. these are the steps i took to getting itunes to work.
1. uninstall all things apple and itune related items off the computer
http://support.apple.com/kb/HT1925 (use this file to find all items needing to be deleted and erased from recycling bin.) (also make sure you do this just as you turn your computer on this way you wont have to worry about exe. files that may not be allowed to delete.)
2. http://support.apple.com/kb/TS2363 (take these step and instead of deleting just one delete all the files you want no trace of itunes or apple on computer this includes quicktime)
3.(this step may not be necessary but defrag and disk clean up "C:/" defrager and disk clean up, when using disk cleanup clean all files so check everything off.
4. Now restart your computer once all files have been cleared and recycle bin has been empty.
5. before downloading any itunes go to E internet explore not mozilla or any other internet service just use E. go to tools. advance tabs scroll down this list to security. uncheck the box that says (check for server certificate revocation*)
6.check to make sure in this same location that (use ssl 3.0) and (use tls 1.0) ARE checked.
7. Mozilla fire fox maybe a better internet service than E its self. so if your using mozilla sorry dont. download itunes from E and do not save just run. install like necessary. when installing i turned off allow automated updates.. let it install.
Try it it out now. i hope this worked for you as it did for me!!!
2 day and some many hours trolling and looking for answered even called apple services for help and rthey kept sending me the same files ive read thousands of times.. so this like i said this is what i did mixing everything ive read together and it worked.

Do you have a profile lock file in your profile folder? If so, delete it and see if TB runs properly:

I attempt to open a second window from the icon but it does not open then when firefox is closed it will not reopen because it is still running in processes but no window displayed until you kill the process and then restart firefox.

I attempted to open a new window from the Firefox icon but nothing happens. I then went on browsing and closed Firefox but was later unable to open it. I checked processes and it was already running but there was no window displayed. I am running Windows 7 Professional.
This is repeated any time I already have the browser open and wish to open a second instance.

I close firefox and try to open it again later, it WON'T and says, "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." Firefox isn't running .

After I turn on my laptop and click on firefox it works fine and it opens THE FIRST TIME. So can you help? i DON'T WANT TO RESTaRT my computer everytime and sometimes have to clsoe firefox b/c I'm typing paper and computer goes slow.

Sounds like a "hang at exit" problem. There are several possible causes for that error. See:
* How to stop the running Firefox process
** In Task Manager, does firefox.exe show in the '''Processes''' tab?

** https://support.mozilla.com/en-US/kb/Firefox+is+already+running+but+is+not+responding
* You may need to try Firefox Safe Mode
** You may need to use '''Safe Mode''' to locate the problem: http://support.mozilla.com/en-US/kb/Safe+Mode
**Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes '''before''' starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
** If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it by enabling '''one at a time''' until the problem reappears. '''You MUST close and restart Firefox after EACH change''' via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.
