problem with mouse right-click

Hello all,

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.

Can anybody help?
