I am using a G5 2.5 quad with 8gb RAM running 10.5.2. This machine runs 24/7.
I use Photoshop CS3. (10.0.1)
Today when I started Photoshop it would not load and gave an error message box that says, " The application Adobe Photoshop CS3 quit unexpectedly. Mac OS X and other applications are not affected. Click Relaunch to launch the application again. Click Report to see more details or send a report to Apple."
