Hello and thanks for the reply. Control+Option (if forgot to say that I'm a Macbook Pro user) works to make the bush bigger and smaller. The part I seem to be missing is that up until today I would have a red overlay inside the brush that would show the size, opacity, and hardness of the brush. The red overlay is missing now. If you have any ideas what I did or more importantly how to get the overlay back, I'd love to know. Thanks again.
