I was putting the finishing touches on a Poser 6 scene that I'd spent days working on, when my computer (Mac OS 10.4.11, 2 Gig of RAM) flashed a warning to save fast I was running out of memory.  An instant later Poser crashed.  When I went to reopen the scene, it no longer showed the scene icon but the MPEG movie square icon.  I don't do movies.  I told Poser to open it but nothing shows in the document window.  The light control ball is all black and the parameter dial heading says "Face Room Actor". 

Question 1:  What did I do to make it think I was doing a movie?  How would I have known?  OR is this a case of computer malfunction?

Question 2:  Can I recover the scene?

Any one have a clue??
