I need to be aware of the thumbnails that are selected so that I prevent bad things from happening. For example, I need to prevent the Extraction of Pages from a document if the user selects all thumbnails and then asks me through my context menu (I overrode yours) to extract out all "selected" pages. Having a document with no pages in it does not work well with my application

So, If I could have the page numbers of the selected thumbnails or a count of selected pages or ??? that would be great. Could this be in V3? If I beg could it?
