I am trying to load a GEOTiff produced by the FAA but am having trouble.  The image I am trying to load is in a zip file located at

For some reason, the image seems to load fine, but it never displays, just an hourglass.  The FAA changed the way it created this file.  Is there a setting in the MapWinGIS.Image that will help?

               Dim img As New MapWinGIS.Image
               img.UseTransparencyColor = False
               img.Open(LocalDir & "\" & FileName, MapWinGIS.ImageType.USE_FILE_EXTENSION)
               myChart.DoubleBuffer = True
               myChart.CursorMode = MapWinGIS.tkCursorMode.cmPan
               _ChartLayoutS(theChart).ChartHandle = myChart.AddLayer(img, True)
