I have the problem that anytime I touch the screen with my pen (which is what I use instead of a mouse, being an illustrator) the touch keyboard pops up, even though I have a (bluetooth) keyboard attached. I'd like to get rid of this behavior, HOWEVER, it's mandatory that I have either the touch keyboard or a screen keyboard when i start my tablet in order to be able to sign in to my account. at that point the system does not recognize an external keyboard. Can anyone tell me how to accomplished this: the steps to disable the annoying popup touch keyboard BUT have a keyboard available at startup?

Thanks in advance for any help.
