I'm using javascript window.open to open an .asp page to get some user input.
This window is opened above my current webpage, but is there any way to make
this new window modal so that the user can't access the page underneath it

If there isn't a way to do this, is there any way to know when the new window
is loosing focus (like a onLostFocus event or something similar). I thought
I could use an approach like this to close the window if the focus is lost
