I've installed the Rhino plugin on my new workstation and all seems to work fine (thanks to the Simlab crew for helping to sort out my licensing issues!) with one small exception: My PDF's don't have a thumbnail view in Windows Explorer. All I see is a blank white rectangle.
When I open the PDF, that too shows a plain white 3D window, but if I select a view from the tree menu on the LHS, the view appears and then everything works perfectly. What can I do to make sure that thumbnails are created when I save the file from Rhino?
