Names not clearing from "who is on-line display"?

[BadgerDog]

I seem to have something weird that's just started with the "Who is On" display"...

Here's a typical example....

It's showing on-line members = Bob S, jjackman, newfie1, SwedeShooter, vaughn

However, Bob S seems to be stuck at 2:40pm yesterday reading his own profile and still shows logged in. jjackman was on at 1:40am this mornng and left, but he's showing as still logged in. vaughn was on at 9:01pm and logged out, but he's also showing as still logged in. The other two seem to be logged in currently and are really there.

Is there a way of clearing this buffer, or running a TASK that does, so I can get this part of the display to be accurate?

Second, what would cause it not to reset and clear people's names when they log off? I've never had this problem before....

Thanks
