Closing Windows in the right sequence

[SoftLiban ZAKHARIA Michael]

Happy New Year All,    I am facing a problem with controlling the close of my pop up windows on the internet. I am opening a sequence of window up to 4 of them, and I must close them in the reverse sequence of opening them. And I need for this to work on both IE and Communicator!!   I'm not asking for much, am I. ;-)   Any response that could set me in the right direction would be greatly appreciated. Thanks in advance.
