Subject: 24.0.50; Mouse-2 pastes the wrong text.
Date: Tue, 17 Aug 2010 08:14:02 +0200

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

In the first frame, go to *scratch* if not alread there.
C-x 5 2.  In the new frame C-x b tmp
Select the text "This buffer is for notes".
Move mouse to the other frame and press mouse-2.  The text is inserted
as it should.
Double click on "buffer" (in the line that was just inserted) to select
it.
Go back to the frame with *scratch* and press mouse-2.  The selected
word "buffer" is not inserted, but the old selection "This buffer is for
notes".

To make the word "buffer" be pasted in to *scratch* you must
1. Select "buffer"
2. Move the cursor in *scratch* with mouse-1 to a new place.
3. Then press mouse-2.

Number 2 is a strange requirement for mouse-2 to behave normally.

Was this fixed?

The issue described in the original report seems to be gone, but it
seems like now the workaround (which is also reasonable behaviour) does
not work:

emacs -Q -f make-frame
C-x b tmp

In scratch, left click and drag to select "This buffer is for notes"

Use middle button to paste into tmp.

Double click on "buffer" in tmp to select it.

Left-click somewhere in *scratch*.  [1]

Middle click in scratch now pastes "This buffer is for notes" rather
than the expected "buffer".

It works without step [1].

Please also see discussion under #8996, it's probably quite relevant. As 
I mention there, fix committed under #6872 were only partial, covering 
only a frame switch case.  I've been just patching locally with my patch 
under #8996 for a while, though it's less than amazingly elegant. 
Afraid I haven't given the matter further thought since #8996, either, 
various local problems still distracting me from emacs.
