I am a freelance graphic designer and recently my paint tools have been acting up somewhat. It is highly annoying as I have a couple of projects on and I need them to work properly.
An example is that say I select pure white and use a brush over a layer, it will not paint white. The opacity is fine, I even reset all of my brushes to default with no joy.
Another example is when I even have a white background and I select a non-standard brush with a black colour such as a paint brush stroke style brush, I often click multiple times over the same area to give depth, yet if I do this the colour changes and not darkens.... I am miffed, please offer some advice anyone! Thanks, Tom
