Apple has just released iTunes 5.0.1 through the Software Update utility. This update brings the following changes:

"iTunes 5 features a new even more powerful instant search, including the new Search Bar which helps you find exactly what you are looking for in iTunes or from among 2 million songs on the Music Store, folders for organizing playlists, and new Parental Controls for music, music sharing and podcasts. iTunes 5.0.1 features several stability improvements over iTunes 5."

Several users had complained with the initial launch of iTunes 5 last week, this fix should fix these problems.
