I've noticed another thing that's been happening since about the same time the logout problem started. Before, if I read a thread and then clicked the Back button on IE to go back to the previous board/page, it would remove the "New" marker from that message (having recognized that I already read it) and refresh the page (so newest/updates threads posted at the top). It doesn't do that anymore, and I have to refresh the board to update the New markers and see updated posts.
It's not really all that big of a deal, since it only requires me to do one click, but it may be in some way related to the other logoff problem. This is internet Explorer, BTW, if I didn't say that before. I don't really have much choice about the browser, unfortunately.
I'd also like to add that as much crap as people have given you about censoring stuff, I appreciate that you did it. I work for an agency that monitors web traffic, and I am probably much less likely to be on their "target list" if there's not a bunch of explitives on the stuff I browse.
