All color pickers in the Book, Slideshow, Print and Web Modules work by clicking in the color picker and dragging to the image then releasing the mouse over the color wanted. However, I am not able to get this to work in the Develop Module.
How can I get the color picker to work in the Develop Module?
I tried UNchecking Use Graphics Processor, and the color picker worked normally.
In addition, it appears the turning the GPU off increased the speed of paint strokes!
