I'm seeing how to leave a child window on the parent so that you can not interact on the parent window without closing the child.
I have tried with some scripts that check if the window has focus, that they use the SetIntervale etc but it does not work for me.
Now try to leave an onBlur="self.focus ()" in the body of the child window and if it works, at least in IE, but for Firefox and Chrome it does not work.
Before this I solved it using the ShowModalDialog function, but since it does not work in these 2 browsers either, I had to go to Windows.open (), but it is not blocked anymore.
Could someone help me on that issue ?, I'm mutating an IE8 website to new browsers.
Greetings!
