Update: You no longer need the Hot Fix, Sp-1 has now been released for the Mac and PC. It is the only update you currently need and you can find both here.
I was browsing the Core Painter 12 Site and noticed that there is a hot fix for Mac OS X 10.7. I just wanted to let my MAC user friends know; I’m not sure how long the fix has been out. I don’t see a patch or hot fix for the PC, yet.
