I am running latest version of HEM and FullTiltShortcuts.
If I enable the FTS functionality that automagically moves my mouse to active table, then HEM on occassion (every 5 minutes or so) will randomly move my cursor to a corner of the screen (pixel 0,0 or 1600,1200 , etc)
If I don't run HEM I don't have this problem.
If I don't enable the FTS functionality I don't have this problem.
It is some combination of the two. I would like to run both because this functionality relieves wrist pain and now it is getting worse.
