FAQ:

I am trying to run Emacs remotely after 'ssh -X' to a remote system. Emacs looks okay and I can maneuver and type normally - however when I try to select a line or two to delete, using my cursor and track pad, emacs quits and I get the following error:

X protocol error: BadWindow (invalid Window parameter) on protocol request 38

ANSWER:

Try 'ssh -Y' instead of 'ssh -X'. The newer version of Os X comes with a newer version of OpenSSH, which defaults to more restrictive limits on what X11 operations it will forward. Using '-Y' gets back the old behavior.
