John,
Try this - set up about 10 or even 20 degrees off polar alignment - say due West - align on 3 stars (if you can) and see if tracking is great. If it is - the mount is compensating. If stars disappear in a few minutes - then it isn't compensating.
I don't think the Starbook has anywhere near the smarts of the older SkySensor2000 unfortunately.
