Wacom Tablet and Photoshop Brush size

Quick Tip: Do you use a Wacom tablet with Photoshop to edit your images? Have you setup one of the touch ring functions to allow you to adjust brush or tool size? Does the brush display only as a cross-hair instead of the circle that you expect?  If so make sure the CAPS LOCK is not set on the keyboard, turn it off and the brush interface should return to normal.
