So I seems to have run into a bug.
When I'm posting a reply using the "quote" button on a post, my top "menu" bar changes to what I see when I'm in my user profile, and I lose the useful (home, search, forum index, sponsoring vendors, channels, contact us) menu. The only way to get the top of my screen to reset is to go back to the home page, and navigate back into the forums. Attachments 1 & 2 show the two screen shots of what I'm talking about.
Just documenting the bug, so it can be fixed eventually
