The driver crashes when I try to update the view window of a part inside of Productstream.

I'm guessing this has something to do with creating the DWF file within Productstream. It does not crash when I check-in a part file into the vault within Inventor, which I have set to create a DWF upon check-in. This means I have to close Inventor, re-start it, and re-open the file I was working with in order to use my SpaceNavigator again. Big pain...

Can someone from 3DConnexion take a look at this please? Anyone else run into this problem?
Thanks,
Bob
