VintaSoft Annotation .NET Plug-in Discussions

I am trying to apply some annotations dynamically to a document.

mControl.Images.Add( "filepath.tif", true );

StampAnnotation tool = new StampAnnotation();
tool.Text = "Hello World";
mControl.Annotations[0].Add( tool );

This shows the annotation correctly, in both the annotation viewer and annotation thumbnail viewer. However when I edit the annotation by moving, rotating, or changing text the annotation thumbnail viewer show the original image and the new image. I'm not sure if this is a bug or if I am adding the annotations incorrectly.

After adding the annotation: http://cid-c168d16d5617adf3.office.live ... terAdd.png
After moving the annotation: http://cid-c168d16d5617adf3.office.live ... erMove.png

Thanks for any advice!
