I must have accidentally set something that affected the brush tool. When I select the brush tool and paint on an image, the cursor does not change to a brush rather it is the move tool and there is no circle showing the brush size. Also, same day, in LightRoom when I select the adjustment brush, the circle indicating the brush appears in the margin of the image but disappears when I put the adjustment brush on the image so that I am effectively painting blind. Has anyone seen this and know how to reset whatever I seem to have done? Photoshop CC; LightRoom 5 on an IMAC Yosemite.
