The century mark and fonts

So, I finally passed 100 hits in a day (and I was no more than half of them).  Hooray for me.  So, now that I have such a vast readership, I really need to clean up the look on entries that I paste quotations into.  It totally messes up the font whenever I do that and even though I think of myself as relatively computer savvy, I cannot quite figure out how to get it back to the default look.  I even tried pasting into a plain text reader before pasting into the blog editor, but no luck.  Anyway, if anybody reading this uses Wolfblogs and has a suggestion on how to fix this issue, I'd really appreciate it.
