I observe the following.
Start Emacs and then open two files one after the other, which makes them to appear in two separate frames, say A and B. Position the two frames so that they overlap, say so that the respective active frame covers half of the other frame. Let frame A be the active one and position the cursor so that on its line there is text to the left as well as to the right. Let me call this cursor position x. Now click into frame B to make it active, and the click again into frame A first at a place whose column is to the left of that of x, and then a second time to a place whose column is to the the right of that of x. This yields an unintended selection in frame A.
This behaviour is annoying if one works with several frames at the same time.

Hello.
I can not reproduce this in Emacs 23.3 or the trunk. Can you test the trunk?
Can you reproduce this when starting Emacs with -Q?

Hello Jan,
first, thanks for your response, and excuse my answer being late.
I still can reproduce the phenomena with the latest nightly build of Emacs24, downloaded from http://emacsformacosx.com/builds on October 18.
Here the steps in more detail.
(1) Open Emacs from the finder.
(2) Via Apple-O, open some file, say A, and have the cursor in row 1 and column 1.
(3) Via Apple-O, open another file, say B, and have the cursor in row 1 and column 1.
(4) Position the frame of B so that it has the same vertical coordinates on the screen as B, and horizontally overlaps the right half of the frame of A. The frame with B thus remains the active one, with the cursor position as given on (3).
(5) With mouse1, click on the frame of A at the cursor position there, so that the frame with A becomes active, then click somewhere on the visible part of the frame with B, but at vertical coordinate below row 1, so that, in particular, the frame with B becomes active again, and finally click somewhere in the frame with B, but at a vertical coordinate below that of the previous click and horizontal coordinate in the middle between column 1 and the horizontal coordinate of the previous click.
This gives me an unintended selection in the frame of B.
Starting Emacs from the command line with -Q, but otherwise proceeding the same way, gives the same.
With Emacs23, making a build by myself, I found something to make the phenomena to disappear:
I the file keyboard.c of the source code of Emacs23, lines 1495 to 1499 are:
FOR_EACH_FRAME (tail, frame)
{
if (XFRAME (frame)->mouse_moved)
return XFRAME (frame);
}
I have inserted a new line of code before the closing brace so as to have:
FOR_EACH_FRAME (tail, frame)
{
if (XFRAME (frame)->mouse_moved)
return XFRAME (frame);
return 0;
}
Could this make any sense? I found it just by trial and error, and have no theoretical explanation. In any case, I worked with a Emacs23 build with this hack for several mounts now and didn't encounter any problem,
Thanks,
Konrad

Using this steps, I can now reproduce it, even in the trunk.

As keyboard.c contains generic code and the problem does not show up on X11 for example, I do not think this is the right fix. The problem must be in the NS-specific code.
