IPhoto 6.06 freezes and will not quit

Question

iPhoto freezes and will not quit each time I open it. I recently upgraded to 6.06 but the problem remains. My photo library is just over 3GB.
What should I do?

Answer 1

Those gray squares with the "!" in the middle indicates that the library has lost the link to the original files. It can be caused by moving or renaming files/folder in the iPhoto Library folder via the Finder or an interruption of some sort while the Library6.iPhoto database file is being written to.
Since you've tried rebuilding the library without success you'll have to start over with a new library as follows:
Creating a new library while preserving the rolls from the original.
Move the existing library folder to the desktop.
Launch iPhoto and, when asked, select the option to create a new library.
Drag the Originals folder from the desktop into the open iPhoto window.
This will create a new library with the same rolls as the original library. However dates on the rolls may be different but can be edited as you would the roll title.
Once this is completed you can delete the Originals folder from the desktop and the iPhoto Llibrary folder. If desired, you can keep the older library folder to try other fixes on it.
In the future I recommend you make a backup copy of the Library6.iPhoto file after each import and after doing a lot of editing and organizing in the library. Then if you experience a similar crash all you need to do is replace the damaged database file with the backup copy and you'll be back to the same place in the library as when you make the backup. See the tip at the end of my signature.

TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
