Hyperlink Click event does not fire when inside a ScrollViewer that has scrolled once

Question

In my ebook reader app I very often find lists of chapters expressed as Html links. I am trying to replicate this behaviour in Xaml by using the Hyperlink Click event.

The book contents is within a RichTextColumns RichTextBlock.

The RichTextBlock (and its RichTextBlockOverflows) is within a ScrollViewer.

If the ScrollViewer has never been used for scrolling the Click event of Hyperlinks fires correctly. but after the ScrollViewer has been scrolled once the click event does not fire anymore.

I have created a small program to demonstrate this behaviour.

I will be happy to upload the program to anybody who is interested and can help me.

Please upload the app to OneDrive and share a link to it here.

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

I have solved the problem with the hyperlink Click event. This had nothing to do with the ScrollViewer being scrolled; the problem was that the first page in a book chapter is a RichTextBlock and the subsequent pages are RichTextBlockOverflows.

I was treating the RTB differently from the overflows in terms of which events were enabled, and this was causing the Hyperlinks on the overflows to not fire.
