I drew something with the pencil and let go of the mouse, but the pencil kept drawing even after I let go! It's really, really annoying.
Also, the auto-fix is annoying too. There should be a toggle button or something.

Yeah, I have the problem too :I

But what do you mean by auto-fix?

i just tried and it seemed to work fine.

I think it's your mouse-I use a pen,and if you keep the right clicker thingy,it'll keep going.I don't think it's a scratch bug-it happens to me in any art program.
