As an aside to this discussion, I thought I'd through out a discovery we
made earlier this week.

For months now, people have reported sightings of a 'trashed' cursor in our
product. We only figured out what was causing it two days ago. We relied on
the system provided cursors. Normal arrow, edit Ibeam, watch, and fat plus.

We found that some DA's, and/or other applications running under MF would
issue ReleaseResource calls for all the cursors they had used. This would
in effect 'yank' the system cursors right out from under us! System resources
are supposed to be shared, image if people started issuing releases for
WDEF's, CDEF's, etc!

We've taken to using our own cursor resources now, insted on relying on the
system provided cursors, with the exception of the normal arrow, which in
theory can't be dispossed of.

If anyone else has experienced this problem, prehaps this is the cause. And
for those of you talking about writting cursor INIT's, remember that there
are other applications out there that expect resources to be there, but
don't neccessarily care what color they are.
