If I type CALL while there is a typeout window on the screen (from either DRAW or ZWEI)
and something in the typeout window is reverse-videoed, it often causes the
LISP-LISTENER that I'm returning to, to get a black blob on its window at the
corresponding place (most likely a timing screw somewhere -- but all such lossage
will be fixed in the new window system, right?).  The same thing occassionally happens
with permanent menus.  It is not consistent, in that trying it several times in a
row doesn't always produce the same result (but it is reproduceable).
