Hey people, i'm a switcher and a n00b. that said, i'm having trouble w/ my Logitech MX510 mouse, the only things that seem to work in OSX are the scroll wheel, right and left buttons. i have a foreward/back button, and two others that i would like to assign. i looked in the mouse section of the system prefs but didnt find anything. Am i missing something? Surely this is possible in OSX.
