brush guides disappeared

I use psp8.
I'm trying to use a brush but the little outline thing that usually shows up (to give you an idea of where the brush is gonna show) is missing. I restarted psp8 and my computer and it's still missing. Can I get it back? (it's real useful)

EDIT!!!:: i figured it out. If this ever happens (because, I still don't know why it happened) just access the psp8 preferences (i use docking options under view) click the display and caching tab and click brush outlines
