compose window font choices

Hello,

I'm trying to change the font used in the COMPOSE window of Squirrelmail.  I have changed the default fonts for IE (I sadly *HAVE* to use IE at work), and have looked at all the various options on my squirrelmail system (I do not maintain it) - but no matter what I do, the font in the COMPOSE window is always courier.  I have a great deal of difficulty with this setup, as I am somewhat visually impaired.  I would like the font (really only in the GUI bit that I see - I don't care that much how others who receive the messages see the message) to be BOLD and LARGE.

Any ideas?  Suggestions (clean ones, please <smile>)

Thanks,

Mairhtin O'Feannag
