I've just upgraded from 2004sp0 to 2004sp5 and when I open certain assemblies I now cannot display "shaded with edges" - the button is greyed out (and also the menu option). All the other display options are available.
If open other assemblies the button works again, but not when I revert back to the "problem" assembly.
If I open this assy on another pc still on sp0 then it works fine. I've also tried doing a "save as", to no avail.
Any suggestions? Regards, John Harland
