The reason probably is that PICEM restores the video mode and the
screen contents before it exits.  This is what a well-behaved program
should do, but people who have written graphics programs for the PC
know what a hassle this can be, what with all the different (and
buggy) graphics cards out there.

That is why using `M-!' to run such programs is not recommended.

It is faster, but not ``much faster''.  The only speed gain is that
you save some keystrokes to type the command line after you shell to
DOS, and type "Exit RET" after you are done.  Using any of the
available keyboard enhancers will make this a non-issue, IMHO.
