Not 100% sure this is a DisplayFusion issue, but I figured I'd start here. I'm running Windows 8 with a desktop screen portrait-mode and a 52" Samsung HDTV on the wall. I run the media center XBMC on the Samsung through the same rig as I do my standard PC work on. The computer is a mid to hi-end gaming rig so I know it's more than capable of running both simultaneously.

My problem is: When I installed DisplayFusion XBMC began losing focus on the big screen whenever I do anything on the desktop screen. It still plays, I can hear the audio, but the second screen goes to it's desktop. I've gone through the settings on both XBMC and DisplayFusion but I can't seem to find any settings that might prevent this. I may have overlooked it as both XBMC and DF have a hell of a lot of options.

Thanks for any help ya'll might have!

Nevermind. Just stumbled across the solution. Just in case anyone else has a similar issue. The trouble was with XBMC. In the System Settings go to the video output settings and set it to "Use a fullscreen window rather than true fullscreen"
