Usually when using a tool like dodge or burn or clone, I have a circle that I can adjust size with the wheel on my tablet or using the brackets keys to make the circle larger or smaller.

Today, when clicking any of these tools I have a crosshair. Turning the wheel on the tablet changes the size number in the tool bar, but I just have a crosshair to work with and can't find the circles that used to come up.

Any idea of what I might have hit/changed to make this result?

Thanks in advance for any insight.

Edit, Preferences, Cursors

Sometimes,  when I inadvertently have the  "Caps Lock"  key pressed on the left side of my keyboard... I loose the circle and the actual diameter of my brush size and softness...and I will get  "just the cross-hairs" symbol on my brush... with no indication of brush diameter.  Turn off Caps Lock...and the brush diameter comes back again.
