As you can see, every single thing that is done in Illustrator CS5 on our three Mac Pro computers is being recorded in the Console log as an <Error>: invalid context 0x0
We have two Mac Pro 1,1 and one Mac Pro 3,1 all with 16GB of RAM and running 10.6.4. We upgraded our operating systems from 10.5 and installed the CS5 Design Premium on the same day a few weeks ago. Since then we've been having intermittent kernel panics on all three machines and in my quest to find the source of those I found that every single action we perform in Illustrator, on all three machines, is being logged in the Console as an error. This happened before and after the CS5 update that was just issued addressing numerous bugs, crashes and memory errors. Anyone have any ideas? FYI - I've tried deleting Illustrator preferences, changing the preference file permissions and running a complete system wide preferences repair from Disk Utility. I didn't think a reinstall of the software was warranted because the problem is identical on three different machines, suggesting that a faulty installation was unlikely. Please help! Sincerest thanks! Aaron
