Well in short the mouse isn't very responsive when I click on something once and hold down the left button to drag it around. But even worst, when I hold down the left button many times it'll even double click and I try to drag & drop something like say, either trying to move a window (which'll inadvertently enlarge the window), or a scroll bar in FF (and since I have my task bar docked on the right side of the screen, that means many times I'm accidently opening up apps that have their shortcuts placed there)

Just a bogus problem that I can't get past very easily and it's driving me crazy

I have a Logitech Marble Mouse ( 904360-0403 I guess is the model number)
