Dating Website Support Forum - Webscribble

I've got the chat on my site now and it's cool, except I'm limiting it to paid members and most of my members are not paid. Here's something weird that's happening. It's happened quite a few times. I'll go into chat and it looks like someone else leaves as soon as I get there, like they don't want to talk to me or something. I think it's something about the chat, that if nobody is in there it doesn't update the status until a new person comes in. But it looks rude when it happens:

[The Lounge]: Mutton has entered at 3:00 pm
[The Lounge]: Pamela has left at 3:00 pm
