Once in a while, after typing ^D, I wind up with the videocolor inverted.  I believe the most recent incident occured while ?= was page-swapping/thrasing on some name that wasn''t a defined function.  It apparently flashs the screen at you once to indicate that no arglist information was found, and I happened to hit ^D just about the window-invert time.'
'
The code for FLASHWINDOW and RINGBELLS is suitably interrupt protected (hence isn''t the culprit) -- so who does  ?= use to do the inversion?'
