iTunes 7.3 - Bundled Apps
Last August, this article at Mac OS X Hints pointed out the differences between AppleScript Application and Application Bundles running on PPC and Intel Macs. At the time, I asked if Bundles displayed and worked correctly in iTunes' Script Menu on an Intel Mac--they did not. However, the original poster, Harry Dymond, just emailed me to let me know that iTunes 7.3 (and/or perhaps OS 10.4.10) resolves this issue.
