I know this is not a clear question, but this is the situation. I have a windows application which parse some file( i use TPL here).
If i minimize this application and keep idle for more than 30 minutes, then i cannot bring the application back. I can see the minimized icon, but this wont come back even if i do ALT-TAB. This is in windows 7.
I just told about file parsing, but this behavior may not be related to that. Below is another strange behavior i am seeing.
This is happening only sometimes, which may/may not related to our issue.
Say i have opened any popup window or some applications ( like MS word, IE) from my main form. When I close that popup window/app then the main form will be minimized or some other app will come front. So i had to click the app icon from task bar to bring it back
