I have a perplexing problem with my Mac LC with Apple monochrome
monitor. The system includes a 68882 coprocessor and has 10 Mbytes
of RAM. Running System 7, with 16-level greyscale selected on the
"Monitors" Control Panel I frequently observe the following prob-
lem: an icon which has been selected reverts to black-and-white
on being deselected. On opening new windows I find them to be the
same. Icons which have not been touched still exhibit greyscale
nature. I have 24-bit addressing (32-bit switched off) for this
behaviour, though I haven't tried it the other way. The problem is
scarcely serious, and switching color-greyscale in "Monitors" does
reset it, at least temporarily. Has anyone a good idea what is
going on? Is something worse likely to happen? Has anyone else
encountered this same phenomenon?
