I'm using GNU emacs in server mode under X windows. The problem that
I've found is that when I use emacsclient, and change the mode of the
buffer (say, from Fundamental to Text for editing mail), emacs forgets
that that buffer was a server buffer, and so C-x # does nothing, and
the only way I've found to let the client continue on is to exit
emacs. Shouldn't the server attribute (is it a minor mode?) be kept
when the major mode of a buffer changes?
Relevant stats: Emacs version 18.51 under X11R2 on SunOS 3.5 on Sun 3
machines (varied).
(Is this fixed in 18.52?)

You can always go back to the "Waiting for Emacs..." message and type 'C-c' to kill the emacsclient process -- you don't have to do anything to the Emacs process. --woodstock -- "What I like is when you're looking and thinking and looking and thinking...and suddenly you wake up." - Hobbes woodstock@hobbes.intel.com ...!{decwrl|hplabs!oliveb|amd}!intelca!mipos3!nate

This is a consequence of the fact that almost every major mode calls the function kill-all-local-variables to clear out mode specific settings. This also destroys any other local variables.
