Odd characters in Thunderbird compose of gnupg

I had my friend set up her XP machine with Thunderbird and gnupg, based,
I believe, on directions obtained here ... so I feel she got the correct
pointers.

However, she is here right now, and when I watch a compose window in
Thunderbird, there is, at the bottom

"--"
MZ .. then representations of binary ,,, then "this program can not run
in dos"  then a *HUGE* amount of (likely) code .... then
gpg4win-1.1.3.exe and several lines of likely text prompts

the compose window is therefore huge and email takes a while to get
sliced up for emailing.


How best to eliminate this? A total re-install?

thanks
