<snip> Why doesn't 3 work on the older iBook? Perhaps all that is needed to to upgrade 3, the first version released really stunk. As long as she has a 800x600 or larger monitor, I think it will work. </snip> Last I heard, us clamshell owners couldn't use iMovie3 because our screens are limited to a maximum resolution of 800x600. iMovie3 requires higher resolution. Did things change with the latest update? David Crump
