Re: [Matlab-emacs-discuss] up arrow not working as expected

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Sorry for the multiple emails, but it just occured to me that we are
using an xemacs init.el that is a bit large and old. Maybe there is
something in there that interferes when using newer versions of
xemacs? Is there a sample init.el matlab file that I could test with?

Also, I noticed a font error in the terminal after I had quit out of xemacs:

 Warning: Missing charsets in String to FontSet conversion

thanks,
maria
