4.12.2 de-bugging

[Azdack]

Hello,
With 4.12 I have a back desk after a few minutes playing. I click on the Il21946 icon on my desk and the game comes right back. No error message. I remember that I had that problem with some ohter applications runing under as Itunes for instance: each time Itunes had an update to propose if I was playing with Il21946 the game went back on the desk and I could see the itunes window update...Are there other applications creating that problem?
My config :
2x GeForce GTX 460 from Nvidia
processor : Intel(R) Core(TM) i7 CPU 950 @3.07GHz
Memory : RAM 12
Windows seven 64 bits
