Did javascript open window?

[Webskater]

Is there any easy, generic way to determine if a window has been opened using a javascript window.open command?

Thanks Dave, that's just what I need.
There ought to be a way in these forums where the person who initiated the thread can say "Thanks - that answered my question" without it posting a new message. A box to tick and a little graphic against the thread would do it.

Sometimes great effort is taken to solve a problem for someone, and a thank you is always appreciated but not really necessary.
But if one is happy enough to send a thank you, I think the little effort behind that in their own words are welcomed too.

After thinking about it, would you agree
