[Fixed] Platform not exitin

Are you using a nonstandard dock or something else at the bottom of your screen? They have a habit of having invisible forms that block other things. Have you tried moving the menu (click and drag the PortableApps.com logo) to another part of the screen and then closing it? You can also right-click on the PA.c logo in the system tray or, on Windows 7, the task bar.

Can people experiencing this provide some more information, please:

When does this occur? Right after launching?
If you start the platform with Start.exe, wait for it to come up and then hit X without running any apps or anything else does it close?
When you click the X button, does the pressed-down state of the button show up?
What OS are you on and what path are you installed to?
How is your drive formatted, NTFS/FAT32/exFAT?
Have you tried installing a clean version, temporarily, somewhere else, like right to your desktop? Does that work?
Is anything else running on your system that you could think of that could interfere with it?

I can't reproduce this issue on any OS. I ran it on Windows 2000, Windows XP, Windows Vista, Windows 7 x64, and Wine running under Ubuntu 11.10 and it worked as expected under all of them.

I think I have an idea what the issue could be. It would seem that some other app in your system has a window up that is not properly responding to the platform's broadcast message that fonts have changed. In less technical terms, the platform sends out a note to everything running saying "Hey, fonts may have changed, you should check that out". It then waits for the apps to say "Ok". A misbehaving app won't respond to this. So we'll need to work around it.

Try this. Close/Kill the platform and then rename the PortableAppsPlatform.exe to PortableAppsPlatformOriginal.exe in your PortableApps\PortableApps.com directory. Then download PortableAppsPlatformTimeoutMsg.exe, rename it to PortableAppsPlatform.exe and place it in the same directory. Then try running the platform and exiting. Did that work? If not, try downloading PortableAppsPlatformNoMsg.exe and rename and place in the same location. Did that work?

Use PostMessage to send that message. The call will immediately return without waiting for a return value... which I can't see you needing in this case. If a window never processes the message, oh well. Chances are it's a hung process anyway so who cares.

This has been fixed in Pre-Release 4.1. It was due to some unresponsive local apps not properly responding. It's been coded around. If you are experiencing this issue, you can either manually download and run the installer or use the built-in updater and then kill the platform with Task Manager when you are prompted to close it.
