CC-ing Keegan because Bug #466 describes another problem with ERC and
windows.

Can't offer much insight but processing window-configuration-change
hooks has changed with Emacs 23. So this
(defun erc-track-modified-channels ()
"Hook function for `erc-insert-post-hook' to check if the current
buffer should be added to the modeline as a hidden, modified
channel. Assumes it will only be called when current-buffer
is in `erc-mode'."
(let ((this-channel (or (erc-default-target)
(buffer-name (current-buffer)))))
...
might have been broken for some reason. To verify, someone would have
to try with Emacs 22 and 23 inserting just before the `let' something
like
(unless (eq major-mode 'erc-mode)
(message "Not in erc-mode ..."))
and look whether it triggers.
