Just in case this isn''t obvious or hasn''t been reported.  Dedit doesn''t seem to be properly clearing the window before it repaints, so that you''re left with new characters printed on top of old ones, witch the old ones showing thru under spaces between atoms.'
One case where I have seen this quite reliably is in Switch.  If I have 2 expressions next to each other and switch them, the screen is garbled, gets fixed up on reprinting.'
