AIM Help

[jennomac]

So I use AIM on my Macbook and for some reason, suddenly all IMs I get, the font is really small. It was never like this before and I was wondering if there's a setting somewhere that I can fix all incoming IMs to a default font.

I'd really rather not use iChat or Adium (I'm weird I know) so if anyone has any possible solutions, I'd love you forever.
