The "since last login" time warp feature displays more messages than were displayed when I logged in - and they were messages that were never displayed before so it seems to resolve the issue of some messages "disappearing."

>Update2: It looks like the messages that I've been "missing" now and then are messages that were posted right after I last logged off. I tested it last night and again this morning and both times there were messages posted close to the time I logged off (after I logged off or those that I didn't click the global refresh button to view before I last logged off) that did not display when I next logged in. They do show up when I use the time warp "since last login" though...

I think you nailed it. Say, you stay logged on and there are few new messages. You don't refresh and log off. Next day you will be seeing all new messages except for the few you didn't refresh before you logged off.

This would explain the mystery of "lost messages".
