RE: [h-e-w] ClearType in Windows XP: Dirty Cursor

[Bill Baker]

Thanks for the responses!

I prefer to leave ClearType enabled, since it make such a big difference in
readability on an LCD.  However, I believe the problem (just eyeballing it)
is that the cursor is drawn with a border outside of the current character's
border.  If it were restricted to the space that the currently selected
character occupies, I think the worse of the two problems would be
eliminated.

So I tried compiling Emacs for myself, from CVS, using Microsoft 6.0
compilers, and came up with this problem after about 650 lines of
compilation output:

NMAKE : fatal error U1077: '"c:\Sandbox\emacs\src/obj-spd/i386/temacs.exe"'
: return code '0xffffffff'
Stop.
NMAKE : fatal error U1077: '"c:\Program Files\Microsoft Visual
Studio\VC98\bin\nmake.exe"' : return code '0x2'
Stop.

I won't worry too much, since I already have precompiled Emacs working fine,
but I wonder if it's something obvious.

IIRC, ClearType is disabled in the current version of Emacs (21.2) because
it causes such problems.  Whether or not that's the fix you were looking for
I leave you to decide :-)
