Private message pop-ups

[TDK]

I got a new pm, and every time I come to the forums the pop-up comes up telling me I have a new private message, no matter how many times I click on it or reply or whatever. But only when I initially come to the forums.

Its happened with a few different PMs so far.

Edit: Okay, I disabled the pop up feature, and deleted all my PMs, but every time I come to the site it all goes back! The only thing to suggest the PMs are deleted is if I click delete again it says invalid.
