I have asigned a tooltip to a panelgroup something like

<h:panelGroup   id="panel_ID" ...>

<span....>

<a4j:commandButton .../>

</span>

<rich:toolTip id="Tooltip" for="panel_ID" verticalOffset="2" value="#myBean.Tooltip}"></rich:toolTip>

</h:panelGroup>

The problem is the Tooltip appears randomly placed. It appeares at the bottom right most of the time but in some cases it appears to be placed miles away at the top.

Any solutions for this behavior
