I encountered this issue and found that it is actually not necessary to completely disable the touch screen.
Instead, it is sufficient to "Stop" the "TabletInputService" (with description "Touch Keyboard and Handwriting Panel Service") under Services in the Task Manager.
Interestingly the touch screen remains still operational. This service seems to only provide the onscreen keyboard and related features. Also if one does try to open the onscreen keyboard windows will simply start this service again. So it is a very non-invasive temporary change which is enough to get Aurora's TreeView to work on tablet/touch screen enabled devices.
