Package: emacs,w32

(Filing a report for old item from FOR-RELEASE.)

http://lists.gnu.org/archive/html/emacs-devel/2006-08/msg00439.html

Initial report (todo: verify new font backend eliminates this and other
Cleartype related problems):

    1. emacs -Q

    2. Load this file: http://www.emacswiki.org/cgi-bin/wiki/mouse%2b.el

    3. Customize this face to have a red foreground:
    `mouse-flash-position'. (The default, yellow, is not very visible
    against an emacs -Q background.)

    4. M-: (global-set-key [down-mouse-2] 'mouse-flash-position)

    5. Select some text (e.g. a word), for yanking elsewhere.

    6. Put the mouse on some line of text. Press `mouse-2' and hold it
    pressed. Move the mouse along the text without releasing the button.
    Release it to finish the yank.

    When you press `mouse-2', the yank position is highlighted. When you
    move the mouse, the highlight moves with the mouse. But vestigial
    overlay traces are left behind.

Hi Drew,

Do you still see the bug below? I tried to follow your recipe, but the 
behaviour I saw was sufficiently different from that described that I am 
not sure that my tests are conclusive.

No, I don't see the problem anymore. I think this was fixed long ago, but I just
tested again to be sure. My instructions should also have said to bind [mouse-2]
to nil, I think. 

IIRC, someone else reported a similar bug and that one was fixed, taking care of
this too. I'm not sure of that, but anyway, this is fixed.

Thx - Drew
