cannot reference window.location.href

[ShinCat]

Hello,

I'm a JavaScript newbie with a serious headache. The following routine generates the following error

Error: uncaught exception: Permission denied to get property Location.href

var spawnWindow;
function openSpawnWindow( url )
{
if( !spawnWindow || spawnWindow.closed )
{
spawnWindow = window.open(url,'spawnWin');
}
else
{
if( spawnWindow.location.href != url )
{
spawnWindow.location.href = url;
}
}
}

Invoked in body

<a href="javascript:openSpawnWindow('http://www.cycleforautism.com')">Cycle for Autism</a>

Windows XP, SP1
Mozilla 1.5, Firebird 0.7, MS IE 6.1

Please show me the errors of my ways.

Yours truly,
Ted

It would be a security violation to allow one web page to
read any property of another web page that's opened from a
different domain.

Thanks for the answer. Is this being caused due to authoring on a local
host? I'm running XP Pro with built in IIS running . I wrote the JavaScript
so no more than one window would be spawned from a Web page full of other
links. What does the browser see in terms of two domains?

All your assistance much appreciated,
Ted.
