JavaScript Popup Problem

[Joe Beaven]

Hi,

I have a popup on my website which appears every time someone leaves my homepage. Unfortunately,howver, it appears even if someone visits another page on my site. Please can someone tell me how to change this so that it only appears when people leave the site altogether?

My current code is below.

Thank you.

Are you using frames? If not, I'd just throw the window.open in the onUnload event handler.
