I have photoshop elements 6.0, and a wacom bamboo fun tablet. Today, when I used the default brush (not the airbrush or soft ones) it was transparent and acted like the airbrush. I kept checking all the brush settings, it was on 100% opacity, I turned opacity off on the pen pressure, I made the spacing and fade to 0% and made sure it was on 100% hardness in the brush settings, but still it wouldn't work properly. The eraser works fine, but using the brush tool, none of them will work properly! Does anyone know the cause and solution of this problem, please help!
