[Javascript] popup window close

[Paul McGuire]

I have a real problem I cant get round.

I have PageA.htm and PageB.htm

PageA.htm is a form and onsubmit I open a popup window which displays a
please wait... message.

PageB.htm take about 3 mins to load and as I want the please wait.... window
stays open.

However on the onload handler of PageB.htm I want to close the window. I
cannot get a handle on the popup once the original window opener has gone.
How do I reference this popup in a new page?

PLease PLaease somebody put me out my misery!
