Because the a selection done with the mouse when xterm-mouse-mode is active is not available to X. It is only available to Emacs, so it is possible to use the mouse to copy between 2 emacs windows running in the same terminal frame, but X know nothing about the selection.
I did not realize it had this disadvantage. It is a serious one. I think we should put the default back to off. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
