The situation is as follows: Intel-based iMac running 10.5.6 iPhoto launches normally and without error in the main (original) user account. When subsequent accounts are created and logged into, iPhoto is shown on the dock and finder with the generic app icon. When clicked, the icon bounces once, and nothing happens. All other iLife apps operate normally. Once switched back to main user account, iPhoto icon shows normally in the dock/finder, and operates normally. Here's everything I've tried, to no avail: Starting the computer in secondary account rather than main repaired disk permissions rebuilt directory (via disk warrior) created several test accounts, and found that iPhoto never loaded in any of them Deleted com.apple.iLife08.plist from Library folder deleted iphoto preferences from each user/library/preferences The only thing I haven't done is reinstall ilife, the reason being that I don't believe it's an issue with iphoto itself, but rather a directory issue. If anyone has any suggestions or advice, it would be very appreciated!
