Changing fonts in Seamonkey Mail panels

[Marc Shapiro <mshapiro_42@yahoo.com>]

I have been unable to find any play on the mozilla.org site to ask this 
question, so I am hoping that someone here can help me.

I am trying to change the fonts used in the various panels in Seamonkey 
Mail.  I am using the same profile as I use for the Mozilla Suite, but 
the displayed fonts are not the same (or the display of them is handled 
differently).  The fonts used by the Mozilla Suite are much more 
readable than those used for Seamonkey.  Changes to 
'Edit/Preferences/Appearance/Fonts are only supposed to affect web 
pages, not the folder and message lists of Seamonkey, itself.

Any help will be appreciated.
