When I try to fix a part in an assembly, suddenly everything just disappears.
I cannot UNDO or get any parts to show up again. The only option I have is to close and lose all the work since last save.
This usually happens when I fix a part in a subassembly within the main assembly while editing the subassembly.
It doesn't happen all the time but it happens to certain assemblies.
