Has anyone tried to add a custom button to the toolbar, which allows a user to toggle between a simple toolbar and a more advanced one?

 

I've tried this and I've gotten it to work, but the problem is that when I change to the more advanced toolbar, the postback event no longer works.  When I try to save from the advanced toolbar, the page simply refreshes and goes back to the simple toolbar, but no postback event is raised.

 

Both toolbar config files have a save button with postback="true" set, so why does one work and one doesn't?  Please help!!!
