ajax error on firefox

[germ]

doing a simple page webmethod call an a page via PageMethods works fine in
ie7 & opera9
the same call on firefox ( and I assume netscape ) generates the following
error :

Error: [Exception... "Component returned failure code: 0x80040111
(NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" nsresult: "0x80040111

}
}


Google turns up a number of references to this problem in general but no
fixes for asp.net ajax in particular.
Since this problem is caused by a problem buried in the microsoft ajax code
I am at a loss as to how to proceed.
Do we just drop ajax for firefox & netscape users until MS puts out a fix ?
Or is there a fix out there that I haven't stumbled across yet ?

so ... what .. is this a dirty little secret that I wasn't supposed to
mention ?

Is no one else using asp.net ajax web service calls or are they just
ignoring any browsers that generate this error ?

ok - just for future reference in case anyone else runs into this issue
the error occurs when the javascript function invoking the PageMethod is
called from a different window
( mozilla seems to be maybe getting confused as to which objects live in
which window ? - or not )

<script type="text/javascript">

var imagebrowser =null;
function SelectImage()
{
. . .
imagebrowser =
window.open("Selector.aspx","Selector","menubar=0,minimizable=0,modal=1,status=0,toolbar=0,width=600,height=600");
}

/*

PageMethods call will fail under mozilla if called from this
function when called from another window : opener.SelectCallback(
selectdURL );
splitting this into 2 functions and using timer to invoke second
part , letting this & functions complete solves the problem

function SelectCallback( url )
{
imagebrowser.close();
imagebrowser=null;
. . .
PageMethods.DoSomething( url , DoSomethingCallback , Timeout ,
Error );
}

*/

function SelectCallback( url )
{
imagebrowser.close();
imagebrowser=null;
setTimeout("SelectCallback2('"+url+"')",0);
}

function SelectCallback2( path )
{
. . .
PageMethods.DoSomething( path , DoSomethingCallback, Timeout ,
Error );
}

function DoSomethingCallback( rslt )
{
. . .
}

function Timeout( txt )
{
alert('Timeout '+txt);
}

function Error( txt )
{
alert('Error '+txt);
}

</script>

<input type="button" value="Select Image" onclick="GetImage();return 0;" />
