Is there some way to save the SHR screen from ProDOS 8, so it can be loaded
into a paint program and modified?  I have tried moving the SHR screen buffer
($e1/2000-$e1/9fff) down to bank 0 and saving it as type $C1, and tried
rebooting to P16 and using a screen saver DA.  Both of these almost work,
but for some reason when I load the resulting file, it has about 6 small
copies of the screen on the image, and the palette is messed up.  Anybody
know what's happening?

Also, I've noticed that after G)oing to a subroutine from the monitor
and returning with an RTS, the registers (ctrl-e) are not what they should
be at the end of the program.  Ending with a BRK 00 gets them right,
but that's probably nor a good idea.

Thanks for any help
