I am on sw2010 sp5, and on a brand new dell with12gb ram and 2gb workstation vram, so the hardware "shouldn't" be the problem. So anyway, I recently created this exploded view, and now suddenly in trying to work on the exploded config I can't select anything in the graphics view, including trying to manipulate the explode lines 3d sketch. Actually, if I click where the unexploded assembly would be, I can select things that way, but the parts aren't there, so it's like shots in the dark. Of course I can select from the feature tree, but that is extremely cumbersome and also unreliable, that acts goofy too. Anyone hear of this and maybe even have a solution? BTW I did reboot and it's still the same. Wire frame, still the same.
