Wacom Graphire Tablet Jitters with Win2k and Tiger 133

[Mahavira_Khan 0]

I am running Win2k on my Tiger 133 and I can not get my Wacom Graphire Tablet to work right. Everything installed fine as soon as I pluged it into the USB port, but unfortunately the crusers just jitters and jumps across the screen. It is simply not useable! My brother has an Abit 133A Board, which I think has the same chipset and controler for the USB, and it works like a charm on his machine. Nice and super smooth. So why can I not get it to run so nice on mine? Does it have to do with my MB? Any help would be wonderful!! 8)
