When I am in a large community area (e.g. "Enterprise Guide" and I click the "<< Message Listing" link to go back to the listing, it goes to a page other than page one (Today, I've seen pages 141 and 24 come up several times.)
I am using Firefox 42.0.
(I tried to attach screen shots in a .docx file, but they were rejected with "The contents of the attachment doesn't match its file type.")
