Hi John,

Dynamic repositioning of the RadToolTip's callout was introduced in the Q1 2009 release. The idea behind this functionality is that the tooltip callout positions better when the tooltip is near the edges of the screen. This new feature works well when the tooltip is shown vertically on the right or on the left but in some scenarios when it is rendered horizontally the callout is mispositioned. This needs further research and more complex algorithm of repositioning and that is why for the time being we have decided that in such case, the callout should be hidden and I assume that this is the issue you report.

 To revert to the previous behavior - override the method which repositions the callout. All you should do to achieve this is to include the following script on your page:

 

 
    <script type="text/javascript">     
        Telerik.Web.UI.RadToolTip.prototype._adjustCallout = function()     
        {     
        }     
        </script>
