Hi, Regarding mavet1's problem, I can confirm that this also happens for me (K45VM, v4 hardware). It seems that this is caused by the "Tap drag" feature:
Sometimes it triggers even while the cursor is moving. I searched through the plist options but couldn't find a way to disable it. I always use only double tap to drag, so disabling "tap drag" would fix the problem for me. Once again, thanks EMlyDinEsH for your hard work on this.
