[fixed] Command execution is interrupted if cursor moves fast when Tweak is on

How didnt i saw this before???

<<Can you test the previous release 2.1.3 or 2.1.2>>

No problems found here: the commands are just executed if user LMB click (="Accept"); they arent interrupted by something "supernatural" ( ) in the app. I've tested with and without Tweak, using various mouse interactive commands.

I've tested inclusive the performance comparing these two releases and 1.5.4 one.
