The opacity won't stay completely opaque for the brush. I have opacity and flow set to 100%.
When I paint in Windows 7 photostop cs 5.1 and 6, I get these semi transparent brush strokes that overlap each other, which shouldn't happen. It should be a gradual build up. I have reset photoshop settings, reinstalled photoshop, changed driver. No change.
The issue is with the opacity jitter so I think its a driver issue since my older intuos 3 worked fine with it.
I used to be able to achieve this, with thick globs of paint that were easily blended together.
