I have just installed my new Graphic tablet and a strange behavior appears to me in Illustrator CS6.
The old day I used to pick my brush or any drawing tool and choose my stroke weight and the brush definition then I start drawing peacefully.
Here I set the brush weight to 2cm and a basic brush profile:
Now I couldn't do that. Every time I pick any drawing tool and set the stroke weight and brush definition, the moment I start to draw those settings reset their values like those appearing in the following screen capture. Just as if there is a default locked value and I couldn't change whatever it did.
Here Illustrator reset my above setting and changed it to 0.0353 cm and set the brush profile to 3 pt round.
I reset my workspace and even I detached my graphic tablet and nothing happens.
Do you have any idea what's going on and how to solve this problem?
