The trackpad on my husband's new MBP seems kinda of jumpy (for lack of a better way to explain). The trackpad on mine seems smooth and I am running Tiger. His is running Leopard. There just doesn't seem to be as much control with his. Has anyone else had this problem or am I just imagining things? I realize that I probably haven't explained it very clearly, but my trackpad just seems more precise. Thanks for any insight or guidance.
