in iphoto when i select a slideshow the dreded pinwheel starts and iPhoto does not respond. Why?
These are your options:
1. Restore the iPhoto library from the most recent backup that predates the issue.
2. Repair or rebuild the library.
3. Scavenge the library with iPhoto Library Manager independently of iPhoto (Library ▹ Rebuild). Books, calendars, and slideshows won't be preserved.
