Sorry, I misunderstood you, then.

Were you suggesting a way to implement mouse pointer shape control in
the MS-DOS port?  If so, I decided long ago not to, as I didn't see
any reasonable way to do that, and didn't think the DOS port is
important enough to have this feature.

The gory details are that on plain DOS machine, there's a system call
to modify the pointer shape into something other than a horizontal bar
of some height, but doing so causes the character under the pointer to
become unreadable (it's replaced by the mouse pointer).  On Windows
(and most DJGPP users run DJGPP programs on Windows these days), the
mouse pointer is what Windows creates, and I know of no way for a DOS
program to request that the pointer shape be changed.  Faced with
these problems, I decided not to implement the feature.

If someone has ideas how to implement this, I'm all ears.  I'd also
consider some emulation, but the emulation should have some
resemblance to the mouse pointer, not to the text it hovers above.
