I have a problem with my photoshop CS3. At first the pen preasure work but now after I change the brush setting. I can't use pen preasure anymore. And the brush picture( I choose brush stroke), it didnt look like the first time I used it (gradation in both side of the brush stroke). I tried to set pen preasure in opacity and size. I once read that photoshop setting can be set to default by deleting a file because the file always created at first when it doesn't exist. Thanks for your help.
