Virus scanning programs were the bad guys for me concerning this problem, especially Avira Antivir which just ignores my setting of only updating once a week... try to shut down your antivirus program (shouldn't be a problem offline) and see if it works.

Hello, guys

Closing the antimalware might reveal if it is causing this, however it is risky. Some malware are waiting for this opportunity. Also, if something bad is in development within the computer, then being offline won't stop it.

Shut antimalware at your own risk.

AVG has given some IL-2 lovers quite the headache that other defense programs don't. It might be time for a new defense. Keep AVG until you find better.

Some guys accidentally and unknowingly push the Windows key while in IL-2. This would certainly reduce the sim to the Task Bar. I've done it myself a few times. The Windows key is of course usually found between the ctrl and the alt keys at the bottom row of keys. I have seen it in other spots on some keyboards.

I hope this helps.
