I thought it was my imagination when this happened the other day to custom brushes I had loaded into PS, but then it happened again today...both with brushes and with new actions I had created. Has anyone had this happen?

I'm running PS CS2 on a Mac that has Leopard (I know...I know...). Could my system be to blame?

Hmm.. that is weird. Generally the only time that ever happens to me is when it it shuts down due to an error, I assume that didn't happen or you would have mentioned it. I am googling to see if I see anything..
