If you're an
iWork '06 user, Software Update has a couple of presents for you: Pages 2.0.1 and Keynote 3.0.1.
About the Pages update (direct link): "addresses issues with charts and image adjust. It also addresses a number of other minor issues."
About Keynote's update (link): "addresses issues with three-dimensional charts and textures. It also addresses a number of other minor issues. This update should be installed on all computers that share your Keynote 3.0 files, so that textures display properly."
