I'm currently using mootools and lightbox2

Mootools seems to be in conflict with lightbox2. Is there a way to change lightbox around so that lightbox will execute?

Currently, the lightbox will not execute, instead, it just takes you directly to the image itself. But if I remove the mootools.js file, lightbox will execute.

I'm using a menu that uses Mootools:
