1. Select "include in projectors" for the Xtra under Modify->Movie->Xtras. This method seems to periodically crash projectors running in Mac OS X straight 10.3.
2. Don’t do the above. Leave "include in projectors" un-checked. Then, manually select any Xtra files along with your .DIR files in the projector-building dialog box. This method of including Xtras doesn’t crash projectors.
