private message pop-up

[Slapyo]

On my homepage I have it display how many new private messages there are and how many total private messages they have. It works perfectly and displays the proper information. However, if you have pop-up notification turned on and then you visit the message board, there is no pop-up to notify you of the new private messages. I have included a few files such as global.php and wonder if the code for determining if it should pop-up or not is in one of those files.

Anyone know how I can get the pop-up to display on my homepage if the user has pop-ups turned on? Which files I need to include and the code.

Thanks.
