3dconnexion on MacBookPro and Parallels

[TabulaRasa]

Hey!

I'm working with Wildfire 4 on a MacBook Pro 2.4GHz and 4GB RAM. My
VM is Parallels which i allowed to use about 2.8GB of RAM (upper limit of
Parallels recommandation). Perfamance settings are optimized for the
VM.
I'm running Windows XP Pof 32Bit.

Thats my hardware with which I had no problems using ProE so far. Then
I bought the SpaceNavigator from 3dconnexion and i couldn't work with
it fluently. I've delays of about 1-2 sec when moving an simple part. But
only with the SpaceNavigator, when i move the part with my mouse it responses immediately.

Does anyone use an similar configuration without problems or has an
idea to solve this problem? Otherwise i'll send back the Navigator and
keep on working with my mouse.

thanks, TabulaRasa
