I do: windowA = window.open(.....)
From Window A, do open another window call B with
I do: windowB = window.open(.....)
So I have 2 windows open.
I CAN edit the Page in window A, and put code in it.
However, the Page in window B can not be edited.

My Question. When someone closed window B, I want window A to close.
Remember, the code to to this MUST be in the page in Window A.
I need something From window a...
... a timer loop, testing to see if Window B is still open?

Any ideas?? Thanks
