A large circle appears around my cursor when I try to draw on a page. I prevents me from drawing in the circle and when I move the mouse out of it, it is slowly drug behind the mouse and a line (corresponding to the tool I have selected) is created. I have gone into configuration settings and turned them all to default however, the circle stays. I was wondering if this was a setting that I somehow clicked and now I can't remove or if it is a bug. I am fairly new to this software so any help would be great.
