We've been using this for some time without problem, but it has recently it has stopped working, possibly due to the latest update of vB(4.0.5)

<div style="margin:20px; margin-top:5px">
<div class="smallfont" style="margin-bottom:2px; width:852; height:26"><right><font color=#bb0000><b>&nbsp;</b></font></right>  
<input type="button" value="Show Spoiler" style="font-size:10px;margin:0px;padding:0px;" onClick="if (this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display != '') { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = '';   this.innerText = ''; this.value = 'Hide'; } else { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = 'none'; this.innerText = ''; this.value = 'Show'; }">
</div>
<div class="alt2" style="margin: 0px; padding: 6px; border: 1px inset;">
<div style="display: none;">
{param}
</div>
</div>
</div>

Any advice?
