TaskDialog MainIconHandle

I'm having a problem with the TaskDialog MainIconHandle.  I'm trying to assign a 32 pixel icon to the TaskDialog MainIcon and it will not show.  While I can get the icon to show using the API method provided in the example, I cannot see why CodeJock's own control cannot deliver the handle.  The code I am using is,

   
    Dim imgIcon As ImageManagerIcon, lngIconHandle As Long
    Dim td as TaskDialog

    Set imgIcons = MyForm.cjImageManagerIcons
    Set imgIcon = imgIcons.Icons.GetImage(ID_TASK_DIALOG_ICON, 32)
    lngIconHandle = imgIcon.Handle
 
    Set td = MyForm.cjTaskDialog
    With td
        .MainInstructionText = "CJ image handles do not work."

        .MainIcon = xtpTaskIconCustom
        .MainIconHandle = lngIconHandle
        .ShowDialog
     end with

    Set td = Nothing
    Set imgIcon = Nothing: Set imgIcons = Nothing

The only thing showing up on the TaskDialog is the MainInstructionText.  The image in the ImageManagerIcons is an XP icon with multiple sizes.  Is there something I'm missing?  Thanks for your help.

Sincerely,

John
