Just figured out that it doesnt work until it looses focus and requires you to check the checkbox/uncheck/recheck it in order to have it get in sync.

I have tested it on IE6 and IE7 so far with IE 6 only requiring the loss of focus one time.

<form enctype="multipart/form-data" id="upload">
'...
'...
<input type="checkbox" name="acceptterms" value="0" id="terms" onchange="handle_button_state();" />
'...
'...
<input type="submit" class="button" name="sbutton" id="{$editorid}_save" value="$vbphrase[submit]" accesskey="s"  tabindex="1" />
</form>

<script type="text/javascript">
function handle_button_state()
{
    var el = document.getElementById('upload');
    if (el)
    {
        if (el.acceptterms.checked)
        {
            el.sbutton.disabled = '';
        }
        else
        {
            el.sbutton.disabled = 'disabled';
        }
    }
    else
    {
        alert('blah');
    }
}
</script>

I changed it to the onclick event and it works better and also added the onblur and onfocus but I cant get it to disable the submit button on the first time page load? I used onload but nada.
