Tooltip Erratic In RadRotator

[jfs67]

RadToolTip will work, sometimes, on the first page load and only on the first mouseover event inside a RadRotator FrameTemplate using the markup I have.  It does "sometimes" work, if only once, so I suspect I am missing a setting.  Here is the markup, there is no code behind:

<asp:XmlDataSource ID="XmlDataSource1" XPath="rss/channel/item" CacheDuration="300" runat="server">
</asp:XmlDataSource>
<script type="text/javascript">
    function ClientShow(){alert('ClientShow');}
    function OnClientBeforeShow(){alert('OnClientBeforeShow');}
    function OnClientHide(){alert('ClientHide');}
    function OnClientBeforeHide(){alert('OnClientBeforeHide');}
</script>
<radR:RadRotator id="RadRotator1" DataSourceID="XmlDataSource1" runat="server" FrameTimeout="2000" TransitionType="Scroll" FramesToShow="5"
    height="200px" width="200px">
    <FrameTemplate>
        <a id="title" class="title" runat="server"><%#XPath("title")%><br /></a>
        <telerik:RadToolTip ID="RadToolTip1" runat="server" Sticky="true"
            TargetControlID="title" OnClientShow="ClientShow" OnClientHide="OnClientHide" OnClientBeforeShow="OnClientBeforeShow" OnClientBeforeHide="OnClientBeforeHide">
           <div id="desc" class="desc"  runat="server">
                <div class="desc_inner">
                <%#XPath("description")%>&nbsp;&nbsp;&nbsp;
                <div><a href='<%#XPath("link")%>'class="link">Read more...</a></div>
                <br />
                </div>
           </div>
        <br />
        </telerik:RadToolTip>
    </FrameTemplate>
</radR:RadRotator>

If you could help get this working, I would be very thankful!

It is inside a template.  So I removed the TargetControlID attribute in the markup for RadToolTip and did this in code behind:

Protected Sub RadRotator1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.WebControls.RadRotatorItemEventArgs) Handles RadRotator1.ItemDataBound
            Dim titleDiv As System.Web.UI.HtmlControls.HtmlAnchor = CType(e.Item.FindControl("TravelDeal"), HtmlAnchor)
            If Not (titleDiv Is Nothing) Then
                Dim radToolTip As Telerik.Web.UI.RadToolTip = CType(e.Item.FindControl("RadToolTip1"), Telerik.Web.UI.RadToolTip)
                If Not (radToolTip Is Nothing) Then
                    radToolTip.TargetControlID = titleDiv.ClientID
                    radToolTip.IsClientID = True
                End If
            End If
        End Sub

Still not behaving reliably, though.

I did not mention this is inside of a DotNetNuke module.  Now the control works intermittently when I stop the application, build, run and navigate to the tab where the control is.  IF it is working, it stops working if I do the following two things:

1. Stops working after page refresh.
2. Stops working after a link in the tooltip has been click, you are redirected to another page, and then you use the browser back button to get to the rss feed.

*EDIT*

I went into the module settings and disabled Caching for the module.  Things seem to be working now.  Thank you.
