Same here. I use Photoshop CS Vers 8. Did security update and *poof*. Constantly crashes when I try to save and save as.
Tried completely deleting Photoshop and all related preferences and folders in the Library. Even tried booting in safe mode. NADA, still bonks out. Looking to see if can uninstall update if that's even possible.
Glad (I think) I'm not the only one.
Also tried repairing permissions and PRAM reset. zilch-a-roo.
