Supposedly, this so-called gem is worth an Akai Deep Impact.. don't know why, it suck ballzaks but I can't complain, it was only 24 bucks at the time.. I'm having a tough time locating an Apple driver for it to utilize the right two buttoms.. back in the day when I would use it with my XP unit, they would let you go back and forward on your browser pages.. I kind of like that feature but it doesn't have any driver for it.. Does anyone happen to have the file for this? Some of the sites that I have looked at don't look safe at all and MS doesn't support the trackball either.
