The require command should only get run when you start emacs. It doesn't
get called with every file you open. When you open a regular txt file,
does it start in ess-mode? If that's happening, you've probably got something
funny in your .emacs - check for lines with (setq auto-mode-alist ...
that might be setting txt files to open in ess-mode.

Cheers,

Tyler
