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!
msconfig
to disable all startup item then check again
