Mouse in QNX chuggs along.....

I just found my old QNX cd (6.1.0), and for some reason whenever I go to use
the mouse, it eats up processing power (50-70%, is that normal?), and the
mouse chuggs around to an almost completely useless state… I thought it
might just be the mouse settings, but that wasn’t it. I had it installed on
a PC before, and I didn’t have the issue… Any ideas would be
appreciated!
