Thanks for the information. (I just used the countries map you provided with the demo code so I'll look for some less detailed maps.)

Just out of curiosity, what would the # of map points have to do w/ converting a screen point to a Geo coordinate point?

Nothing, but the hit testing does. When you move the mouse over the map, hit testing is done to determine which country is under the mouse cursor, so that we can highlight it and/or show some additional information in a tooltip.
