That problem drives me crazy for some days now and I just don't know what caused that.
When I try to draw a brush it does not use the grid I have chosen. It uses the 1 unit grid everytime, regardless of th actual grid size.
Two questions: Why? And, how can I fix this?

Is "snap to grid" turned off?

Screw that, I hate my stupidity.
Seems like I turned it off width the SHIFT+W shortcut.

Thanks.
