Design Library not showing preview thumbnail

Maybe it's a new funtion or option that I can't seem to find,but ever since upgrading to 2009 SP1.0 and now 2.0, I no longer geta thumbnail image in my design library.



Notice that the images are showing for designs that were createdand saved prior to SP1, and now the new one "Monster Snap Frame" isworking as predicted in weldments, however, no preview.

This is typical of the six or so designs I have saved, so it's notunique to this library part file.

Thanks in advance
