[Mac-emacs-devel] Mouse Face Failing to Clear Bug Fix

[Andrew C. <ak...@cs...>]

Hi Everyone,

With the patch emacs-21.1-2-mac.patch.gz for building Emacs 21.1 on
Mac OS X, you should be experiencing the following problem.  When the
mouse is moved off any text with a mouse face (highlight property),
the highlight is not cleared automatically.  This problem can be seen
when you use M-x customize or M-x list-faces-display.

Please try the following patch for the file src/macterm.c.

Andrew.
