Good point Descalzo! In my opinion, this subject (not ‘a problem’ but sometimes exasperating, specialy with stressed hands :-) is more important than the “Move cursor only”. “Move cursor only”, and other ways do deal with pointer, are interesting as prefs. This “Double-click” issue is a basic function!
Perhaps would be nice to have the opportunity to check a box saying something like: “Act as ‘double-click’ with 5 pixels tolerance”…
