OS: Windows 10

Hi,

Thanks for this great software. I like it very much. I use it under Ubuntu 18.04 with no problems with my XP-Pen Artist 12 Pro tablet.

Now I have a problem as a customer project forces me to use Windows 10. Installation was flawless and using the tablet with my pen and my mouse works also. But after I have pressed one of the pen buttons my mouse stops working: I can use it in other programs but in xournal++ pressing the mouse buttons has no effect. After restarting xournal++ the mouse is working again.

As a workaround I have tried to disable the pen buttons and use the shortcut buttons on the tablet for switching between eraser and highlighter, but this is also not working. It seems that the signal of the pen buttons is influenicing the mouse behaviour even there is no action assigned.

Using the same szenario with e.g. MS whiteboard works.

Is this a configuration problem or a bug?

TIA,
Guenther
