Brush Problem

[KimMoore]

Hi Damien,

I have turned my computer on this morning to do some editing & my brush in photoshop isn't round like it normally is.  I have added a screenshot, but un-sure if you can see this?

It is in a cross & I can't seem to make it bigger or smaller.

That's because its size is so big.
