Deleting brushes in PSP9

This is going to sound particularly unintelligent.

I have both PSP7 and PSP9. I can load brushes all day long and then use them whenever I please. All is well. In PSP7, I can also delete brushes when their use has expired. However, I do not see a delete button in PSP9, which makes me somewhat angry. I've even gone into the Program Files, and deleted the brushes manually, however the brush still remains in the program. Would I have to export each individual brush?

I couldn't find anywhere else to ask such a humiliating question.


Any help?
