Something like this happens with other programs I'm using as well, except they don't minimize. When I use MS Word, play MegaMek or World of Tanks, the window randomly becomes inactive. It happens intermittently. I haven't found a pattern to it or anything with key presses.
What could be causing this?
I'm running Windows 7 Home 64-bit, MWO 64-bit client. This also happened with the 32-bit client.
