Please compress larger files like the one you attached before sending
them to a mailing list.  There are people (including me) who are using
dial-up connections with 56k modems for accessing mail and news.  In
addition larger mails might get filtered by the mailing list software.

You might also want to get a decent mail reader which sets appropriate
MIME types.  `application/octet-stream' for plain text attachments is
a nuisance.

It also happens in Text mode.  If you open your file in Text mode and
activate Flyspell mode and Longlines mode with your settings, resizing
the frame and trying to scroll will trigger the hang.  So this is not
related to AUCTeX.
