A recent AVG and Avast antivirus update is preventing DisplayFusion 9.9 from launching on some systems. If you're running into this issue, please update to the latest DisplayFusion 10.0 Beta.
I am having troubles when using DisplayFusion and GoToMeeting at the same time. If I have DisplayFusion running I can not share anything through GoToMeeting - it simply says that screen sharing is paused. The only way I can share is to stop DisplayFusion.
