Using the Gradient tool, I can click and drag a gradient on a layer or layer mask, however the controls that allow the gradient to be adjusted and repositioned do not show.
This is the same whether 'Gradient' or 'Classic Gradient' is selected.
If I want to adjust the gradient I have to draw a completely new gradient until a get a gradient that I like, there is no way to adjust or reposition a gradient as the gradient controls (if they are there) are not visible.
