Why does right-clicking create an orange dot in the center of the circle?

Question

Why does the first widget example in kivy lead to an orange circle in the middle of the yellow one when you right click on the canvas and a pure yellow one when you left cli

Answer 1

It's multitouch emulation, you can see how to disable it here

http://kivy.org/docs/api-kivy.input.providers.mouse.html

Answer 2

To disable multi-touch emulation, add this to your source file containing your main function, before any other kivy modules are imported:

from kivy.config import Config
Config.set('input', 'mouse', 'mouse,multitouch_on_demand')
