continuous trace of the brush

[cumbaraquimbara]

Hi

I´m working with brushes and classic tools. Suddenly the brushes don't give me a continuous trace as they usually do. They draw a circle like when the brush is down only one time. Maybe I select something accidentally, I don't know what, and that's why all the brushes are working like that.
How I return to the "normal" mode to make lines and traces with the drawings tools??

answer:

I selected "one point dot" in the main panel.
