Choppy navigation

Hey guys, so I am currently using v1.1 but have installed the trial versions of v2 and the same problem happens.

the best way to describe it is when I am navigating around my model in any view mode (split, 3d, left, right you get the idea)
the software is sluggish and is constantly jogging to catch up.
its a major drag on working my workflow.

I have several other 3d apps that are running smooth and no issues.
I am using winxp pro, latest service pak and wireless logitech mouse. ( tried using a wired mouse and same problem).

thanks
Mike Fitz
