PM Box issues.
 

I am getting emails saying that my PM box is full. However I know that it isn't.

It is empty...

Sent PMs are also included in the total number of PMs. Try clearing out the "sent" PMs.

or make sure you are looking at them from 'the beginning'.

That worked. I didn't know the sent PM's collected.

For curiosity's sake, HOW MANY DID YOU HAVE IN THERE?!?

Probably 100

Quite a few. I didn't really count them.

I have my User Control Panel set to pop an alert when I receive privates messages, and I'm allowing popups from tfproject.org in Mozilla's popup manager. For some reason, a private message sat in my inbox for ages today before I just happened to squint at the fine print on the index page and noticed I had a new message. This was working fine last week, as evidenced by the fact that I got popups several times during a brief exchange with another member. Have I done something since then to mess it up? (There are only two messages total in all my folders, so I know I'm not over the quota.)
