clickLinkWithText doesn't work w/cursor wait

[elmerr]

I have a javascript function:
<script language="JavaScript">
    function goTo(actionVal)
    {
        document.body.style.cursor = "wait";
        window.location=actionVal;
    }
</script>

The link doesn't work with the cursor="wait" line.  If I comment this out, it works fine.

Has anyone run into this before?

Httpunit versions:1.5.4 and 1.6.

Thanks.
