Before I start, very nice work!



In the DWT Outline on navPage, the twisties are stuck in their initial position and don't flip when the content does.



I've found that the best way to get this to work smootly is to display both icons and hide the one that is not appropriate.



So, at build both icon elements, but only display the appropriate one.



In the onclick event, its a simple matter of turning 'this' off and turning either the next or previous sib and turning it on.
