Good morning, David.

I have some additional questions that go along with this topic, which I hope you'll be able to answer.

You mentioned issues with loading WANG annotations at different points in the WebAnnotationViewer's life cycle.  With that in mind:

1.  Do these issues occur with XMP annotations, too, or just WANG?
2.  We have a viewer that is required to load multiple documents (a document represents 1 multi-page tiff file in our document management product) in a virtual queue without causing a postback after the initial load of the viewer.  Is it possible to load annotations using Remote_Invokable functions in tandem with the WebThumbnailViewer.OpenURL() method, or is a postback necessary in order to load another queued document along with its annotation data?
3.  Given that the control handles XMP data natively, would it be better to simply convert all existing WANG annotations in documents to XMP?  If so, is there a way to directly test the type of annotation in a tif file, or do I have to make an assumption about the annotations stored in the documents?

 Thank you very much for your time on this matter; this has been an informative thread so far, and I look forward to any response you might be able to offer regarding my questions.
