Interesting. Yeah, "last visit" doesn't make any sense basically... just noticed it now. I use the same bookmark but with "show content since: last month". Sometimes I have less time and check only a few threads, sometimes I have more time and check almost every thread. If you choose "last visit" you basically have to check every thread, as they will disappear from this search upon your next action. Yeah... sorry, can't really help you with what's wrong, I'd just suggest to do what I do and change "last visit" to a time frame (I picked "last month" because when I'm travelling I sometimes can't check the forum for days and that way it still gives me an overview of everything that happened).
