Please let us know if you still run into any trouble after updating.

Ok, what about if you disable the Application Hooks in the Settings > Advanced Settings window and then restart DisplayFusion? I apologize if it sounds like I'm stabbing in the dark, but I more or less am, since I can't reproduce the issue here, and the debug logs weren't helpful :(

Just trying to narrow down with feature(s) in DisplayFusion might be causing the CPU to constantly be in use.


Disabling application hooks does not change the CPU issue.

I think I'm experiencing something similar - I just updated DisplayFusion to 6.1, and now its eating up 3-5% of my CPU at idle, significantly more than 6.0 (although 6.0 was also pretty bad). Unlike siliconman I'm running Windows 7 x64.

Disabling the taskbar and application hooks have made no difference to the constant CPU load. I'm going to see what else I can turn off to see if I can narrow things down further.

I have that problem also when the DisplayFusion automatic update starts. Its now in a loop. Everytime the auto updater says new version 6.1.0 Beta 5 is out, because it keeps installing 6.0.1 Beta 5.
