>This place has always had a bug where if it's been a day or two since you've logged on that the upper pane won't properly show all messages since your last logon, it typically truncates to messages posted before midnight.

Thats not a bug (If I understand the problem). There is a ComboBox up there is it has been multiple days, so instead of seeing 2000 messages, you see 200, then go to the next day and hit Retrieve, then you see the 300 messages for that day.
