Change settings Laptop DELL + DELLPEN end shapr3D

Good day to all you developers and users of shapr3D
Please help.
Previously, I installed shapr3D on my DELL LATITUDE 7400 2-in-1 laptop, and set it up as for using a computer mouse, and over time I got a DELL ACTIVE PEN stylus. But I can’t fully use the program with a stylus, since the program is installed for a mouse. In the settings, I didn’t find any parameters that would change such a problem. I even reinstalled shapr3D, but it didn’t help, since shapr3D remembered the previous settings.
Please help me!
Thank you!
P.s. The shapr3D program is just great!!!
