This become a arse

Probably because you have a new PM.:lol: If it doesn't show a new PM, hit F5/Refresh until it shows up...
 
I've had a window pop up quite a few times about a couple months ago and it said I had a new PM. I would look and there would be nothing. :odd: Oh well, I'm glad it doesnt do that anymore.
 
You're probably looking at cached pages (that were cached at times you did have a PM). Refresh the page and you probably won't get it again. :)
 
Maybe it pops up a window when you get a PM. Go to "My GTP", "Edit Options", then cycle down to the pop up a window when you get a new PM bit and hit no.
