I was bored and downloaded the free version of Krita. So far, it has really helped me as for the most part I have been drawing like garbage, and now it looks pretty good. Anyways, I selected calligraphy after drawing for a while just to test it out. I went back to the default brush and whenever I try to paint it just drags the canvas. Well, it looks like it's trying to drag the canvas, yet it stays still. Every other tool works except for the default brush. Please help me and thank you for assistance.

Hm, that's strange... Does it make a difference if you select another tool?

Actually, I fixed it now. Thanks for the reply though.
