I'm using iTunes 4.6 and OS X 10.3.4, for some reason I'm unable to rename tracks. Clicking on the track name does nothing, if use "get info" I can't edit anything in any of the text fields. I've tried deleting prefs, deleting the library file and reimporting, repairing permissions etc. but still can't edit any text fields. Just tried reinstalling iTunes still no go. Any ideas?
