hi,
IE4+ doesn't support the
window.stop
method. Instead, the
document.execCommand
method has an (previously) undocumented argument called Stop, which
allows you to call
document.execCommand('Stop')
to get the same effect as
window.stop()
in Netscape.
It should be noted that using this repeatedly in IE 5.x (especially
within frames) can cause a browser crash.
