This might be a common problem (altough I did not find any reference to it anywhere) but I can't right-click my mouse in D2. I have a (standard) logitech pilot mouse, and when I right-click (eg in the source editor) the menu just flashes very quickly. I haven't even had the chance to see what's on the menu. It's not due to logitech's 'mouseware control center', since I have identical problems whit that disabled.
