MS versions 3.0.3 - 3.05 do not respond to Stylus on Microsoft Surface Book

Musescore 3 has worked fine on the Microsoft Surface Book (Windows 10 laptop), up until version 3.02. Now there is no response to the pen (except the "right-click" operation). This is very strange, because it works fine with the trackpad and how would MS distinguish what kind of 'mouse' hardware is being used ? I have uninstalled and re-installed numerous times, and the results are 100% consistent: The problem appears in versions 3.03, 3.04, and 3.05. My work-around is to re-install 3.0.2 on the laptop, while continuing to update on my desktop PC. I will continue to test every new version on the laptop, of course.
