popping up windows is problematic! People don't like them and modern browsers may block them! You'll get better results by doing a hidden div that overlays the whole page, then using simple javascript to show that div when you need to

just change the div's style.display to 'block'

getElementByID('thehiddendiv').style.d... = 'block'

and to hide it again (like a close box) set it to 'none'

As a click though internet policy page, I'm tring to get Firefox to open without the address bar. I'm not concerned about circumvention, the intended patrons have little computer skills. I have studied the source to security.symantec.com, but it only opens a Modal window after you click. I want it open that way as the home page, then after one clicks agree, it will become a regular browser window.
