OK I have some really weird PM random bug stuff going on. Here are a few of the issues that I've noticed:
- When I get a new PM, it shows up in my Inbox. If I try to read it from there, however, half of the time I'm told that the message does not exist and it gets moved to my "Archives."
- Half of the time that I read a PM, there's no option for me to "reply" to it from within the PM; I have to send a new PM.
- If I go into Archives and read a PM, there's a 25/75 chance that I'll erase all of the PMs in that folder (this just happened).
There was something else but I can't remember what it was. Anyway, the PMs appear to be quite buggy! 
- Oh yeah! If I get a PM while I"m in the forums, and it shows up in the upper-left of the screen near the three icons, under my forum name, and click on the "1 unread PM" it practically does nothing. The page "blinks" -- looks like it reloads but doesn't actually refresh the page. So I basically end up in the same spot I was before clicking on the link. :p
Edit: OK this is getting a bit annoying. Nobbers just sent me a PM. I tried to read it from INbox but got this message when I clicked on the subject:

I went into the message via the Archives folder, and when I clicked on "REPLY" I received the same message in the screenshot but now my Archives folder was showing 0 messages.
I'm using FF2.0.0.12 on WinXPsp2 btw....
