-EDIT-
nevermind.
now, when I try to save the set it will only let me save one brush to the set O_o

and when I click one brush in it

Hold shift to select them all.

that didn't work :|

Try cntrl?


Either one works. You hold cntrl/shift and just click which ones you want to save. Hold while clicking.

oh it worked thanks a lot kristina! shift didn't work for some reason O_o

Oh, weird.

Anyways no problamo.

I suppose I'll close this.
