Post subject:  Buggy scrolling in WPF DocumentPreview Control

There is a bug with mouse wheel scrolling in the WPF DocumentPreview Control was first referenced in two posts Thomas Hoevel on May 10, 2012:

This works with the WPF build of the Document Viewer (there's a little bug: scrolling stops when the mouse cursor is over text; keep the mouse cursor over an empty area (e.g. page margin) and scrolling will work).

That was almost 7 years ago, there has been no news since, and it's still not fixed in the latest PDFsharp-MigraDoc-wpf NuGet package (1.50.5147). My customers have mentioned it several times as an annoyance.

Is there a place where I can submit or elevate this bug? Or better yet, release the code so I can fix it myself?

Thanks!

Well I"m happy to find the source code available on Sourceforge: https://sourceforge.net/projects/pdfsharp/files/pdfsharp/PDFsharp%201.50%20%28beta%205%29/

I will look at it and attempt a fix. Is there any way to publish my fix besides posting it here on the board?

Publish the changed files here if you resolved the issue with the current source files. Always good to have a working sample that allows to try the changes before merging them.
