Two backgrounds are defined in the local coordinate system. The first one is binded by default. The test then sends a false event to the active Background node. This should cause the second background to be the currently binded background (and be moved to the top of the stack) and the first background to be move from the top of the stack. The second background should then start sending true events (via the is_Bound field). These events are caputure and use to start a timer. The test should generate blue sky image with some text flashing on it. The test can be started by clicking on the text displayed when the test is first started. PLEASE NOTE THAT THE SECOND BACKGROUND IS NOT FORCED TO BE THE ACTIVE BACKGROUND BY SENDING A true EVENT TO IT, BUT BY SENDING A false EVENT TO THE BACKGROUND AT THE TOP OF THE STACK.'/>
