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]
Editing iCal Events in Snow Leopard
Snow Leopard makes looking at event details in iCal easier. In the Leopard version of iCal, you had to double-click an event to reveal only some information in a pop-up box; you then needed to click the Edit button (or press Command-E) to edit an item's information. In Snow Leopard, choose Edit > Show Inspector (or press Command-Option-I) to bring up a floating inspector that provides an editable view of any items selected in your calendar.
