Default Question on screen protectors

I always install a Zagg Invisible Shield on my phones and tablets. Question on the Note 10.1: will installing a screen protector affect the s pen functionality? I am buying this tablet mainly for drawing with artflow/sketchbook pro. I am assuming that the screen protector would interfere with the s pen when sketching. Anyone have one installed that can verify?

EDIT: Obviously this should be in the accessory forum. If I mod wants to move it, that's cool. My bad.
