Space Navigator SE

To All,

Recently upgraded to Solidworks 2009 SP3 - having issues with SpaceNavigator SE 3.7.12 - my system will crash on large assemblies.

My system is as follows

Intel Core2 Extreme CPU X9650 3.00GHz-3.33Ghz - 8.88 GB RAM
NVDIA Quadro FX 5600 ver 6.14.11.7846

I miss the Space Nav - use it for the last two years on SW 2007without iccident - also 3DConnexion or several other forum have noanswers.

ThanksSolidworksEdrawings
