Sorry to bump an old thread, but I've been intermittently getting the same issue where the DisplayFusion taskbars stop responding and the executable is sucking up CPU. It's happened twice today after upgrading to 10.1.1, and Sophos is the anti-virus I use.

Been seeing this behavior as well radomly as well , multiple times a day. No consistant reason I can find.

Loaded up the new beta version today hope that helps.
