That works, both C-x C-c and C-x 5 0 exit the emacsclient frame, and SSH does not hang/refuse to exit in either case. I will use --with-x-toolkit=no from now on, thank you! Somehow I missed that recommendation (maybe you can point me to it?). I have always avoided GTK for "emacsclient reasons" but I thought Lucid would be OK. Can I add something like the attached to etc/PROBLEMS? Thanks, Thomas
