Hi Camu, thank you for the prompt reply.
I remember trying to fix this problem before and must have seen your answer previously, because when I went to make the change you suggested, it was already there:
Just to be sure, I took it off, saved, then put it back and saved again. I disabled my cache and reloaded the page and got the same result as my original screenshot. I've tried loading that page in firefox and IE and it's the same in both.
I noticed that that field for inline CSS has moved from the Options tab to the Comments form tab, which I assume is just a cosmetic change? Either way, it doesn't appear to be working. :-/
