To have the popups appear on top:
Make sure you have the .focus part in the JS code. Something like:
on (release) {
getURL ("javascript:NewWindow=window.open('yourPage.html','newWin','width=400,height=300,left=0,top=0,toolbar=0,location=0,scrollbars=0,status=0,resizable=0,fullscreen=0'); NewWindow.focus(); void(0);");
}
The NewWindow.focus part - tells the window, which you gave an instance name earlier in the code (NewWindow=window.open part) To have focus - meaning to appear on top of all other windows. If that was NewWindow.blur(); instead, the window would be opened behind the other windows.
To Not have (or to have a title bar) - make sure that toolbar=0 in the code above. To include it you would have toolbar=1. ie Yes = 1, No = 0. You can also just specify Yes or No - but on some browsers (mac) it's better to use 1's and 0's then specify yes or no.
