javascript popup customization

Hi, I have a javascript script that popups a "message window" on bottom right hand corner of browser, which is just some css to make it look like a message. it performs a [login to view URL] to produce this. This script works perfect, when you load page it popups the "message windows" What i need done is a delay, I tried using setTimeout, and it works, but after the delay it [login to view URL] the "message windows" and removes all the over content on the page. I need the content on the page to stay intact and have a control over the delay. Should be very quick, to anyone who knows javascript fairly well. ## Deliverables id liek to have this done same day, as its very small change
