There were a couple of problems that could cause this effect under
some circumstances.  I've fixed them, and will post a new version
soon (after finishing a couple of other changes).

It currently clears the screen with a VioPopup, which doesn't allow any
kind of graphic display.  I'm experimenting with using a PM window, but
there are some problems then with getting it to return to the correct
session after you touch a key.  If I can resolve this, a future version
may have some other options for the display. If somebody posts me
(public domain) C code it is more likely than if I have to go figure out
fractals etc. myself.  (I like the random moving lines display I've seen
on other machines personally.)
