I've noticed this as well and have been looking at it.  It looks like the problem is confined to the "What trail am I on" thread.  Since I hadn't made any code changes, I'm wondering if it has something to do with the length of the thread.

Anyway, I'm looking into it.  I think I'll start a new thread for that topic....

I made a tweak to the configuration of the forum, and it appears to have fixed the issue.  Not sure why it cropped up all of a sudden, but I think it is fixed.

If you see more odd formatting things, let me know.

Rob,

Thanks for making it work again.
