I have a Dell Latitude E6530 running Win 7 - 64-bit
I mouse left-handed
When I swap the button functions so I can use it comfortably, what you would call the left button produces a right-click submenu half the time. It acts like it is doubleclicking sometimes as well.
This behavior is not there when I have it set up right-handed.
The dell touchpad control dialog has the right-handed button definitions, however it seems to mostly use the mouse dialog config.
Has anybody else seen this kind of behaviour?
