I have this strange problem where Windows (7) is just changing focus all the time.
I tried using the Focus.exe (http://www.happydroid.com/focus)
it shows every time this happens the line:
No foreground application
and then comes back to the last focused window.
In other words - it's not a program that's stealing the focus (!)
But maybe Windows itself...
Tried Process Monitor, Process Explorer and Windows Event Viewer - Nothing unusual there.
It's impossible to use editing software and games like that...
I'll add more information when I'll have it.
Thanks in advance!
