Stupid question about "Clone Stamp" tool

I am new to Photoshop and I have been using the clone stamp tool. When using, it was displayed as a circle which I could adjust the size of. Now all of a sudden the "circle" is no longer there. I can still use the clone stamp function but without the circle, which came in handy because it showed the user the area size that was going to be affected by the clone stamp. How do I get the "Circle" back. Thanks :)

You most likely have Caps Lock activated. Just hit Caps Lock again to de-activate cross hair cursor.

It could also be that you are using a big giant brush size.

But it's probably the caps-lock thing.

or delete your prefs (corrupted prefs can cause this)

Or change the cursor type in the "good"prefs" back to cusor size.
