[jQuery] $.post callback broken in safari in new window.open()

[Thomas Bircher]

hello

I'm opening a new window with window.open()
In the new window a file is loaded with the following post data
function:

function ajaxPost(url,data){
        $.post(url,data,
        function(data){
                alert(data)
        });
        , "json");
}

If I call this function form within the new window everything is fine
- If I call it from the opener window the callback function is broken
- only in safari - ff works fine.

any work around for this?

1000 thanks
