    Go figure, I try for 4 hours, then solve the problem 5 minutes after I post on the forum.

    The issue seems to be that you cannot call add_menu_page or any of those functions from outside the class. You need to call add_action(‘admin_menu’,array(class,function_to_setup_menu));

    Then in function_to_setup_menu, use add_menu_page().
    Here is a code sample:

    <?php

	//Set Up Class
	if (!class_exists("B2BannerRotator")) {		

    	class B2BannerRotator {

        	function B2BannerRotator() { //constructor

				}

		function Main() {
				return 0;
			}

		function ConfigureMenu() {
			add_menu_page("Test", "tesT", 6, 'b2_bannerrotator', array('B2BannerRotator','Main'));
		}

       	}
   }

	//Create new instance of class
   if (class_exists("B2BannerRotator")) {
          $b2_banner_rotator = new B2BannerRotator();
   }

	//Actions and Filters
	if(isset($b2_banner_rotator)){

		// Administration Actions
		add_action('admin_menu', array($b2_banner_rotator,'ConfigureMenu'));
	}

?>
