Close remote doesn't work in Mac/NN

[hsil]

I'm trying to open then close a remote control window using code like:

function showRemote() {
self.name = "main";
var windowprops = "height=420,width=524";
OpenWindow = window.open("xxx.htm","remote",windowprops);
}


And:

function closeRemote() {
timer = setTimeout('window.close();', 20);
}

I've set up a test at

Fiddled with the code in lots of ways. No problem with Win or Mac/IE, but in Mac/NN the remote will not both close and redirect the main window.

Any help is appreciated,
Howard
