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.

Automatically Disable/Re-Enable Screen Saver

This function works best when run via a Window Location rule. When the application specified in the Window Location rule is launched, this function will disable the screen saver. After the program closes, the screen saver will be re-enabled.
