Apple has posted iTunes 9.2.1, which fixes some bugs found in iTunes 9.2. You should note that Apple says the update disables older versions of some incompatible third party plug-ins, but doesn’t say which ones.
iTunes 9.2.1 requires Mac OS X 10.4.11 or later to run. You can update via the Software Updates component of the Mac OS X Preferences app — or from the Apple support web site (http://support.apple.com/kb/DL1056?viewlocale=en_us).
