Sometimes it works sometimes it doesn't - I haven't been able to find out any pattern to when it works and when it doesn't. I have it set to pop up a message when I recieve one, but it seems that its not always working, sometimes I look down and see it says I have 1 message, then I'll go to it and it was something that was sent over a day ago. Maybe its something on my end. But it isn't real good when someone PMs me about an offensive post and I don't see it my first visit to the board since the PM.

I understand your concern however there is no custom setting for PM pops in vB, perhaps just a feature that will become more reliable with vB 3...

Really? In the Edit Options part of User CP there is still an option to pop up a box when you have a private message?

Of course, I meant some admin setting like frequency of pops or something.
