Phil, I have this same problem when using my SuperMac 19" monitor and
the spectrum-8 color card for it.  You will be able to use MacsBug if
you are running in 2-color mode.  This is a known bug.  I am told it
is because macsbug doesn't use quckdraw to do its screen drawing, so
it doesn't always work on all monitors.  In fact Macsbug is actually
running on my computer when it is in that gray mode, I just can't see
anything.  It does respond to the es commands and rb commands!
