I'm using 

if (remoteWin && remoteWin.closed)
{
	// Window closed
}

I've noticed in testing that if the pop-up is blocked by various pop-up
blockers, remoteWin doesn't exist (actually, it was set to null) and that is ok,
but if I tried to access the closed method and the handle was null, I would get
a Javascript error.

It's not. I'll file that away for later use.

Yes, I agree. However, contracts signed with company providing site being loaded
in this remote window require the exact window.open command I'm using.

Agreed. Since I use FireFox (with TabBrowser extensions -- not sure which piece
causes the pop-up to open in full window), I get the full window myself, along
with all the menu bars. I don't like when pop-ups load anything less than the
full window (don't mind the sizing, as long as I can resize).
