Bzzt!  Wrong.  The AI Driver actually eor's with four different colors, just in
case color #0 is black.  But, when you eor #$ffff, change the data, then
eor again, the new data is STILL changed.  Saving the old data produces a simi-
lar result.  The only way I can think of to overcome this problem is to check
if we're writing to the graphics screen and turn off the indicator light if
we are.
