two cursor problems on Mac OS X that seem to have been around for manymonths now...
1) start emacs from the most recent CVS using Emacs -QM-x diredwith cursor on some file name, move mouse to be over it.  thegreen highlighting erases the gray cursor and it is not seen even aftermoving the mouse away
2) M-x set-cursor-color black: the character under the cursor is notseen.  That is, the character does not show in inverse-color under thecursor.
please let me know if there is any additional information I canprovide...

[Message part 1 (text/plain, inline)]

[ resent from emacs-devel ]

Hello:

This is my first patch submission to Emacs.  I'd be happy to learn how to do it better in the future, if you have any comments or criticism.  The patch was made against the bazaar repository.

Thanks,
Will

== Description: ==

A first draft at patching bug #4831 (23.1.50; cursor problems on Mac OS X), specifically part 2, where characters under the cursor are not seen.

Modified the drawing routines: 
* the cursor will be drawn with the frame foreground color if the cursor color is the same as the current face background color or the frame background color.
* the text over the cursor will be drawn with the frame background color if the cursor is a filled box, and the cursor color is the same as the text color

== Copyright ==

I happily assign copyright for this code to the FSF.  Please do with it what you like.

== src/ChangeLog: ==

2010-07-23  Will Roberts  <wildwilhelm <at> gmail.com>

        * nsfont.m (nsfont_draw): Change the text color if needed to be
        distinct from the cursor color

        * nsterm.m (ns_draw_window_cursor): Change the cursor color to be
        distinct from the text color
