ahh great – look forward to the resolution as it looks a little unsightly! Thanks 
Upgrade to BuddyPress 1.0.2, and read this post: https://buddypress.org/blog/news/buddypress-102/#comment-1173.

Thanks for that Tracedef!
I forgot to upgrade the Buddypress Support plugin in bbPress as well! *bangs head on table*.
The thing that threw me off was the version number of the BuddyPress bbPress plugin; it was the same as in BP 1.0.1, so I thought I didn’t need to upgrade!
