I am using Photoshop CS3 and have a slight problem with the color scales. When I drag a photo into the program, the colors remain. As soon as I create a new layer or move the photo, the color scale changes from RGB Slider to Grayscale Slider. I have tried clicking on RGB Slider but it does nothing. I cannot figure out how to get it back to th RGB Slider. I have attached a photo of the scale I am talking about.
