Hi ! Trying to resolve a SOUND problem in 1.2, I switched to 2.0.3 which was a successful step for that problem. But the new version seems largely slower with EGA graphics and CLS does no more blank the bottom of Screen 9, leaving the instruction line whatever parameter (0,1,2) is used. OK, drawing a foreground filled box does the job but it looks as a bug anyway ! Using Windows 10 64 bits 20H2.
