When using the option to display in a registered application, the document is displayed in the native application, not the plug-in, so the right-click menu options are for the native application only.

To check out a document in this native view, simply right-click anywhere to the right of the icons on the PaperVision Document Viewer Control tool bar.

This will provide the standard right click options that one would normally see when right-clicking on a document within the plug-in.
