Safari text issue

I've been having an issue for a while now on some sites, mostly a few webcomics, where some of the text is scrambled. When I posted Hope, I encountered the same issue with the title, which was in Helvetica font. I switched it to Georgia, and that cleared it up. I've seen the same issue in only one other place here on BC, which is the line under the chapter number on Portia Bennet's stories.

I'm using Safari, on both an XP and Vista machine, and getting the same effect. Internet Explorer doesn't seem to have the same problem, but I have other issues with it. Does anyone know why this is happening? Or if there's anything I can do to fix it?

EDIT: The latest Safari update corrected this problem.
