The user interface / window does not appear when running an Adobe AIR application after recent AIR runtime update

Hi there:

I have developed some air app that can run normally on three PCs (Windows 7 , 8 and Mac OS 10.6.8) without any problem, but it suddenly cannot run after recent update.

For some app, the UI doesn't show up after double click the app icon and the app cannot be found in the task manager.

I tried to uninstall them but uninstaller said "It is running".

For some other app, the UI doesn't show up after double click the app icon, but the app can be found in the task manager and run as a process.

Re-install the app didn't help.

Re-install the AIR runtime didn't help.

Did anyone else has this problem and know what is the reason ?

Thanks.
