Rollover menu adjustments

hey all,
please take a moment to test the code below; creating a kind of interactive rollover menu with some effects. the original code used Math.PI to create a radial menu and i’ve modified it into a vertical menu to suit my needs.

what i can’t manage to do right now are two things:

  1. test the movie, and you’ll notice that the spaces between the items (menu elements) are not equal. what causes that or what am i missing here?

  2. i’ve set a global onPress function that links to a certain URL. how should i set an onPress function for each menu item individually, so that each item on the menu can be set to link to a different URL?

your help will be much appreciated!
