I've been running Solidworks 2009 and later 2010 successfully on Windows 7 since the betas and RC's.  To overcome some sluggish performance issues with my graphics card on Win7, I updated the driver by downloading the latest from Nvidia.com.  Since then, all my Explorer thumbnails are totally black, and anything I print from the model view, is also black (going through black toner at a great rate of knots!)

Anything I need to do to overcome this in Solidworks, or do I simply roll back the driver and put up with sluggish performance? (currently running 195.39 beta)
