monitor trouble

[CENT at MIT-AI (Pandora B. Berman)]

cadr7 has an unhappy monitor (which happens to be a vmi); all evening
it has gotten glitches: random transitory horizontal lines going the
wrong color and then switching back. it looks sort of like a horizontal
version of the vertical pop the screen used to give when cold-booting,
but less severe. the glitching doesn't seem to affect anything, it just
happens. maybe this is statyic collecting somewhere? someone take a look,
please? although it doesn't have any permanent affect on screen or output,
it is disconcerting.
