  It seems to me that the image and the VM cannot find the screen
depth that was used in the scaled environment when it went back to the
non-scaled mode.

  Get the "appearance..." menu from the world menu or the show source
menu, and click on "set display depth..."  There choose 16-bit and see
how it goes.

  However, this situation might suggest that it doesn't have 16-bit as
a choice for some very non-obvious reasons, or the depth of the scaled
environment isn't 16-bit (or 32-bit) for some non-obvious reasons.  If
it happens, see what screen depth you have in the scaled display, and
non-scaled display and let us know.  I'd like to see what went wrong.
