setInterval Access is denied

[kopite]

Hi,

The web page runs in IE4 and IE5.5 and reloads every 60 seconds without a problem then all of a sudden when it reloads (this may be after 10 minutes, 2 hours etc) I get an Access is denied error pointing at:

id = self.setInterval('countdown();',1000);

This is the relevant code in the page.

<!-- code -->

<input type=text name=kk value=100 size=4>

<script language=javascript>

var id;

function countdown()
{
jj.kk.value--;
if ( jj.kk.value == 0 )
{
self.clearInterval(id);
gogogo();
}
}

function gogogo()
{
location.reload(true);
}

id = self.setInterval('countdown();',1000);

</script>

<!-- end of code -->

and, replace

<input type=text name=kk value=100 size=4>

with

<form name=jj>
<input type=text name=kk value=100 size=4>
</form>
