I am using the Q1 version of the telerik tools.  After upgrading, I'm experiencing an issue with the modal view of the tooltip.  It turns the entire screen solid gray, rather than a transparent gray.    I'm also experiencing this problem with the RadEditor Image Manager.    The tooltip displays fine in IE7.


Is there a fix for this?  Is anyone else experiencing this problem?



<telerik:RadToolTipManager runat="server" OnAjaxUpdate="RadToolTipManager_AjaxUpdate" ID="ttSigPreview" Width="630px"  ShowEvent="OnClick"   
  ManualClose="true" Modal="true" Position="BottomCenter" OffsetX="-50" AutoCloseDelay="30000" Skin="Default" OnClientBeforeShow="checkSignature"   
        <telerik:ToolTipTargetControl TargetControlID="btnSigPreview" />

Hello Angie,

Do you by any chance examine the page on a laptop? The same problem occurs in some laptops with older version of the DirectX driver or video card (for PC with old DirectX, too, but very rarely compared to laptops) and the problem is related to the DirectX CSS filters under IE. We used them in order to achieve a transparent modal overlay. The other browsers do not use that Activex component, as they have utilized pure css opacity, and respectively the problem does not occur if you use them. In this case I recommend you reduce the page size in order to make the page works properly. Also, you can use the non modal RadToolTip control and avoid using any animation on the page. All of the transparency animations use the same DirectX filters under IE and may cause the same problem.

As you understand, we cannot override that behavior that occurs in your case and what we can suggest is one of the following:

  1. Reduce the size of the page.
  2. Update DirectX drivers
  3. Do not use moadlity if you scenario allows this.
