Cannot use scroll bars with a stylus

Hello Scrivener team!

I am sometimes using the program on my Cintiq, and I cannot scroll within windows using the stylus. Scroll bar is highlighted, but it attempts to resize the window, doesn’t actually scroll. Also, I cannot click anywhere above or below the scroll bar to navigate up or down in the window. It just tries to resize.

I’ve entered Scrivener into Wacom properties manager, but it made no difference.

All these actions are just fine when done with a mouse, so I am mystified.
