The following steps will allow you to change scenes seamlessly without having to confirm the change:

1.  Go to the SETUP menu
2.  Go to the GLOBAL tab
3.  In the first column, select "Scene Load" under the "Confirm Pop-Ups" heading
4.  Press the encoder under that column to de-select Scene Load - the box will no longer be orange

This will allow for scene changes without having to confirm that change.  This also allows for scene changes from the iPad without having to come back to the board to confirm that change.
