I can't believe I am the first, or only, person running into these
problems, but I don't find anything directly in the archives.  This
thread appears to be closely related, although it seemed to die out a
few months ago.  I am not an assembly programmer, so the discussion thus
far was not too helpful.

I am very new to DJGPP, having downloaded and installed the software
about a month ago.  Everything is working fine except for these problems
with grx23.  I am running on a 486/66 under Win95 in a dos window.

Problem #1:

System crashes on GrMouseDisplayCursor.  This happens not only in my own
program, but also when running MOUSETST. Sometimes I will get a Win95
message that an illegal operation has been performed, it closes the
window and tells me to restart the computer.  Sometimes, under RHIDE, I
will get the error message:

	Call frame traceback:
	in function _GR_shift_scanline+99

Problem #2:

CURSTEST also blows up in a similar way with the same error message at
the GrMouseDisplayCursor statement.

Problem #3:

When using getimage in BCC2GRX, the use of any value for x1 other than
zero causes an abend.  Here there is a similar error message except for
the line number, which makes me think it is a similar problem in grx23
and not BCC2GRX:

	Call frame traceback:
	in function _GR_shift_scanline+201

Any help would sure be appreciated.
