This problem started in SW 2008 at about SP3.0. Thethumbnails generated that show in Windows Explorer for drawings areblacked out. Thumbnails for parts and assemblies are fine. Doesanybody have any idea what is going on here? It only occurs on myinstallation. Other computers in the company don't have thisproblem and their thumbnails show fine on my system. It is onlydrawing files saved by me that have the issue. The attached JPGshows the issue. The red arrows show which part goes to whichdrawing.SolidworksDrawings And Detailing
