The above question does not cover the problem, perhaps:

How only to open a new named window,
if a window with that name isn't open yet?

or just:

How to open an URL in a window named 'myWin'?

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

I would prefer a function like this:

function openWin(aURL, aWinName) {...}
