I Fixed It!!!!
ok so I was on this website
http://www.macintouch.com/readerreports/iphoto/topic3812.html#feb01 . I saw the following article and this method worked!
I'm really happy, but a little annoyed that I had to backup and reinstall everything!

Thanks to all for this thread. I upgraded to iPhoto 6.0 with no problems on my G4 Powerbook. When I did my G5, it had the beach-ball of doom editing issue. Or black screen in full-screen editing mode. Tried every normal toss and install procedure, but the problem persisted on the G5. After reading this I compared the two.
The G4 Powerbook (10.4.4) had version 1.4 of and the G5 had version 1.2 of the AppleAppSupport.framework.
Ok, so I tried replacing the plist file mention upthread, and no fix. So I said screw it, and tossed the entire contents of the folder: /System/Library/PrivateFrameworks/AppleAppSupport.framework/ on my G5 and replaced them with the contents of the same folder on the G4.
Success! iPhoto works perfectly on the G5 now.
http://homepage.mac.com/dsjosephson/iphoto6framework/FileSharing24.html That is a .sit file of the 1.4 contents of the directory: /System/Library/PrivateFrameworks/AppleAppSupport.framework/ it will unzip to a folder called /AppleAppSupport.framework toss your older version of this /AppleAppSupport.framework/ un the trash (you'll have to authenticate) Replace with the 1.4 version in the: /System/Library/PrivateFrameworks/ (you'll have to authenticate again)
//Launched iPhoto and edited in every mode with Success! And it was far more responsive. Didn't even need to reboot.
YMMY. Good luck all!"
