Marcus,

Use one circle shape. You can use the MouseUp to know which quadrant was click in. You can use 16 bitmap images to show which of the quadrant combinations have been clicked on.

>I need to use odd shaped objects to represent parts of teeth. I have to be able to click on the shape and change the color. The objects need to be very close to each other on the screen. Does anyone have any experience with this situation? I could get by if I could figure out how put 4 quarter circle objects together to make one circle. Any feedback is appreciated.
