This happened a week ago:
1) Logos opened to a little miniature window below the bottom left corner of the screen:

2) Later that session it crashed. No Logos crash log, and I restarted to quickly to get the others. I've got the Apple crash log if anyone wants it.
3) When I opened again I encountered the 'no layouts' bug (a first for me, but I know it's happened to others):

This time I did remember to duplicate the logs before I restarted. Let me know if you want any.
