PowerPC Interrupt Extension -- If you've been seeing inexplicable hangs or momentary freezes on your Power Mac, Apple might have an answer for you in the new PowerPC Interrupt Extension. Drop this in your System Folder, and it fixes one known cause of "long interrupt latencies" - basically, where the computer sits around waiting for something more important to happen. It's difficult to say what specific problems this extension will fix since so many programs can be affected, but reports indicate the extensions fixes formerly-reproducible problems with some games, telecommunications software (including PPP), and audio/video editing tools. This extension requires a Power Macintosh and System 7.5.5. [GD]
Removing Photos from iPhoto
Despite iPhoto's long history, many people continue to be confused about exactly what happens when you delete a photo. There are three possibilities.
If you delete a photo from an album, book, card, calendar, or saved slideshow, the photo is merely removed from that item and remains generally available in your iPhoto library.
If, however, you delete a photo while in Events or Photos view, that act moves the photo to iPhoto's Trash. It's still available, but...
If you then empty iPhoto's Trash, all photos in it will be deleted from the iPhoto library and from your hard disk.
