Change PopUp's Title in JavaScript

I’m using this script to open another page in popup:

function popUp1(page) {
fineline=eval("window.open('"+page+"','fineline','toolbar=0,scrollbars=0,location=0,status=0,menubars=0,resizable=0,width=442,height=275')")
width=(screen.width/2)-400
height=(screen.height/2)-300
fineline.window.moveTo(width,height)
}

When popup opens the title shows address. How to change title?
