When you have the fireworks window open, look in the upper far right corner and you'll see an "A" next to a check box. Check that box and you'll notice a new line appear in the timeline. This is the Angle timeline. Click in the bar above the lazer that you want to adjust. Then select the "shell" that you've placed to project the lazer. You'll notice a circle and arrow coming out of it and there go. Click on the circle around the shell and slide it around. You'll have experiment a bit to get it just right.
