bug#8421: 23.3; Strange handling of mouse events in Nextstep/Cocoa port of Emacs23

["Jan Djärv" <jan.h.d@swipnet.se>]

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?

	Jan D.

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.
