PM pop up not working?

[pigpen]

I've noticed a few times now... whenever I get a PM, it doesn't always ask me anymore if I want to goto my PM box...

it asks me from time to time, but not always anymore...

I haven't changed any settings... any ideas?

Ya, I've noticed that it missed two messages on me. I really have no idea of where to even look on this one, nothing has changed.

it has to do with how the main forum page is refreshed. sometimes i'll get the popup a few times in a row, even though i've read my pm, because its using a cached main page which says i have a new popup.
