terencegallacher on "Oulipo, first line capitalised"

Hi,

just editing a draft and noticed the opening line of the article is now capitalised, it wasn't before. I looked at the HTML and couldn't see a stray tag, I cut it, re-pasted it 'clean' and reformatted it, the problem remained.

I then looked at my homepage and can see that intermittently several other articles that have been published, have the same problem. Should I conclude that's it's a bug or, have I pressed the wrong button (I can't see how). This 'style change' appears on all 3 browsers I use.

Any suggestions?

cheers
