Thanks for the reply! When I turn on debug-on-signal, I get this:

I'm not very adept with emacs yet (obviously) and it's getting to be really 
frustrating. The first time I tried to use edebug I made a mistake, and every 
time I've tried since, edebug doesn't seem to start after I instrument the 
function. I even moved my .emacs.d and reinstalled auctex, and it still won't 
run. Is there some other place where persistent settings are stored besides 
.emacs.d? Any ideas regarding either problem would be greatly appreciated.
