When I use any full screen program (usually games) it messes up stuff on my dual monitor set up. It messes up my secondary monitor by pushing part of the main monitor over onto it. It blacks out any programs like DivX and VLC I'm using to watch movies. It also pushes all apps off to the right of the secondary monitor. Is there any settings I can change that might fix this problem?
