Hello,
Current version: GNU Emacs 24.4.50.1 (x86_64-apple-darwin13.3.0) of 2014-07-14, bazaar revision: 117528
On OSX, under tmux (and outside), emacs 24.4.50.1 (trunk), the mouse drag to resize pane does not work anymore. (It used to work fine on emacs24.3)
drag and drop pane separation: result in outputing escape charcters in
buffer (ex: [<0;133;27m), error: Wrong type argument: number-or-marker-p, nil
Regards,
