In SW08 sp0 ev using Vista Business, with no documents orother applications open except SolidWorks, in Tools, Options,System Options, the Show Thumbnail Graphics in Windows Explorersetting is checked and grayed out. I prefer to have this turned offso I can see what document types are easily in Win Explorer, and ifI want a preview, I switch the View to Thumbnails.

Any idea why this is on and why it is grayed out?SolidworksGeneral
