My game keeps minimized itself

My game keeps minimized itself the whole night and causes me to disconnect from match lobby game, I am on PC version. Anyone got similar problem or know what's going on?

I know in the past if something on the window pop up, it will cause the game to minimized...and disconnect me from online game (fuck FIFA for this)

Seriously I had better online experience playing the game on pirate third party client in fifa 11...
