emacs won't forget file state as saved by desktop.el

Dear People,

I have a relatively minor but incredibly irritating problem. 

I tried enabling desktop.el. It saves the configuration of the files
to .emacs.desktop. In particular it set in .emacs.desktop (for some
reason I'm not sure of) a file called reject1.tex to come up in
fundamental mode and also come up with whizzytex (which I also
installed) enabled. I disabled desktop.el in my .emacs files and
deleted .emacs.desktop and thought that would be the end of the
matter. But unfortunately not. Whenever I open up reject1.tex I get it
in fundamental mode and with whizzytex enabled (so that advi pops
up). It is really starting to annoy me. I can get rid of this
behaviour by removing whizzytex, but it comes back when I reinstall.

I assume there is some config information sitting on my hard drive
that is causing this, either from desktop.el or from whizzytex. No
other latex files behave this way. Ideas?
