I know about this.  It seems like a bug in the Windows display VxD,
because DOS and full-screen display on Windows both work correctly.

I imagine that the problem is with the emulation of the BIOS feature
whereby, by default, the cursor shape is independent of the character
cell size.  In other words, you can treat a 16-pixel cursor on the
80x25 VGA screen as if it were a 8-pixel CGA screen.  I'm guessing
that the Windows display VxD doesn't support the VGA character cell
size well enough.

You could try using function 12h, subfunction 34h of Int 10h, to
control this behavior.  I don't know whether it will do any good on
Windows.

In any case, this is not a problem with the DJGPP library, it also
happens if you issue raw BIOS calls directly via int86 or __dpmi_int.

As an aside, I suggest to upgrade to DJGPP v2.03, since the conio
functions in v2.02 had several bugs.
