well, as far as i can imagine, you have :
1) an ordinary page - the "parent" one;
2) you open a pop-up from "parent" in a manner, that this pop-up always has focus (modal window), yes?
3) you click on the button in this pop-up to open the 3-rd window, yes? But the popup dominates over it's own child, and the child can not retain focus.
Am I right?
