Font size question

[Paul E Condon <pecondon mail2 quiknet com>]

I am using balsa on a intel/debian installation. I've just gotten 
my email to be
fetched, and now I have a problem. I see the messages in balsa, 
but the font
sizes are inconsistent within the balsa display. The side bar 
list of mail 
boxes and the list of emails in the mail window are controlable 
with the gnome 
control center, but the display of the contents of a email is not 
under the 
control center. And the font in that display is too small for my 
liking. Where
is the control of that font size?

TIA

Paul
