General problem with drawing programs: User running System 6.03 on a MacII with Apple Colour Monitor and Viking large monochrome. Most drawing programs seem to have a problem where freehand drawing is "mirrored" in a number of small areas, across the menu bar. As soon as he starts drawing, about 4 small areas turn white (about 1.5 inches square) and show a perfect simultaneous image of the drawing being performed in the main window. We have tried a few obvious things about removing INITs and switching off RAM cache but to no avail. ?

Used to have this problem with MacPaint on my Mac II colour system. Eventually got a different drawing tool, but found that turning the color setting to black and white in the control panel removed the problem. I believe it is an incompatibility between the colour monitor interface and the assumptions built into the drawing program being used. Just never had the time to chase it any further. Just in case this might help. Mailer bounced message.

Could this be related to the number of bits of color? Change the color setting to 2 bits (black&white) and the problem might go away. -shabtai cdp!sklein@arisia.xerox.com
