Assembling Myself Into A Corner.

I got myself into a solidworks situation which I couldn't getout of. I had to kill solidworks through the task manager.

Here's what I did.
Opened an existing assembly with internal parts. Opened theinternal part and rolled back the feature tree. I then closed theinternal part.

I found myself with one assembly open, which was inaccessible dueto the internal part being in roll-back state. I couldn't open theinternal part to fix it because I wasn't allowed to work in theassembly.

Was there any other way out?SolidworksAssemblies
