Projector window sometimes flashing, going to background

Someone is having this problem too?

Maybe you have a program that goes foreground...

My Antivirus does that..notifications after database updates

I thought that it could be a malware, but after a deep analysis the computer was clean.
I think that there isn't a software conflicting with the projector.
If I discover what it's I will post it here.

Thanks for the tip.

Ah also, when I minimize the windows and click once on taskbar icon it does not maximize again, I have to click like three+ times to it maximize.
