The iTunes 7.6 update has some troubles, AppleScript-wise. I’m not exactly sure where the problem is, however, the first evidence of it occurs with Make Bookmarkable. An “Apple Event timeout” error occurs when multiple tracks are selected. I have posted a workaround and I am investigating the problem so I can file a bug report with Apple.
My hosting company is experiencing some server trouble and as a result–so they report–access to the site will be slow through the day on January 18 while they effect repairs. Sorry about that!
Apple has released updates to iTunes and QuickTime. I’ll be on the lookout for AppleScript features and post info when necessary.
