Checkbox with Tooltip?

Hi,

I added ToolTips to components. It works fine exept for the checkbox. When I add a Tooltip nothing is shown if I point at the checkbox.

Code:

---

<ext:Anchor>
  <ext:Checkbox ID="Checkbox1" runat="server" FieldLabel="Checkbox">
      <ToolTips>
        <ext:ToolTip ID="Tooltip18" runat="server" Html="Tooltiptext">
        </ext:ToolTip>
      </ToolTips>
  </ext:Checkbox>
</ext:Anchor>

---

thx,
Jack

I constricted mine in a renderer and wrapped it in a div with a tooltip and worked great - but there might be an easier way
