FAQ Topic - How do I check to see if a child window is
open, before opening another?
-----------------------------------------------------------------------

var myWin;
function openWin(aURL) {
if (!myWin || myWin.closed ) {
myWin = window.open(aURL,'myWin');
} else {
myWin.location.href = aURL;
myWin.focus();
}
}

Popup windows cause usability problems and are generally best avoided.
