Photoshop CS3 Crashes in Leopard With Quicktime 7.3.1

I have been very diligent about updating my Apple Leopard OS 10.5 to be sure that I can eliminate as many problems as possible. I have also been running the Adobe Updater more than usual hoping that Adobe fixes things with Creative Suite 3 along the way. Well, as software would have it, Photoshop CS3, which had been working just fine, now, all of a sudden, won’t launch. The only thing I can think of are two Apple updates lately, namely Quicktime 7.3.1 and the latest Security Update for Leopard. I suspect that Quicktime is the problem. Since it is so close to the holiday, I have been busy getting ready for Christmas so I haven’t had much time to troubleshoot the problem. But I plan on using Time Machine to revert my system back to last week so see if it fixes my Photoshop problem. The strange thing is that the “unsupported by Adobe” Photoshop CS2 works fine so I am using it for my image editing tasks right now just to get them finished.
