I have a really wierd problem.  I have a 386 with a Quadtel Bios, and
all has gone perfectly, until I tried Cscape (the demo version).  It
works properly, but the mouse cursor is not visible!  By running the mouse
around the table, various things light up, but of course you can't use it
properly because you don't know where you are.  This is so in both text
and graphics modes.  I have Wordperfect, Drawperfect, Quick C, Topspeed C,
Metawindows, and lots more, all of which work perfectly with the mouse.

Any suggestions would be _greatly_ appreciated!

As far as I know, the appearance/disappearance of the mouse cursor, at least
for Microsoft mouse, has to do with INT 33H. Check to see if you have any
hardware/software that uses this interrupt vector as well.

Some mouse drivers have extended video BIOS stuff in them for writing to
EGA registers (since the original EGA registers were read only).  If you
have code that doesn't make use of these calls, that might be part of the
problem.  (ie, code that talks straight to the EGA hardware itself can 
have problems with some combinations of display cards and mouse drivers.)
