[Evolution] Low-contrast (dim) display of forwarded messages

[George Reeke <reeke mail rockefeller edu>]

Dear list members,
   My wife uses evolution email (details below) and all received
forwarded mails appear in the preview window in very low contrast,
such that they are almost unreadable.  These are just ASCII text,
not html.  The surrounding text (the message by the sender who
forwarded the mail, headers, signature, everything else on the
desktop) looks normal.  Anybody have any idea how to make these
text inserts appear in the normal font or contrast level?
   (As always, before writing to this list I checked the archives,
the gconf configuration editor, and did some googling and could
not find a solution.)
   The problem does not occur with my similar setup on an older
IBM laptop.  Her setup is Evolution 2.0.2 under Centos 4.4 =
RedHat EL 4 (old story--can't upgrade because of numerous library
dependencies in RedHat).  We have an NVIDIA 7900 series graphics
card feeding a new Samsung 940 display via DVI if that matters.
   Thanks for any help,
   George Reeke
