wine users - Sep 2010 - Font problem

I run Thunderbird from PortableApps under wine, on a SuSE Linux 11.2 
system and have a small annoyance that I would like to resolve. Whenever 
the less than character is displayed - < it is presented as a small box 
with the characters 003C inside the box... Most other characters seem to 
display ok, just this one is messed up... Any ideas how to fix?  I ran 
winetricks allfonts to install all the wine fonts...
