Karl Ramberg commented on SQ-906:
---------------------------------

Changing SugarNavigationBar>>rebuildButtons to 

rebuildButtons
	submorphs do: [:e | e delete].
	self addButtons

seems to fix it

> It happened with some older projects that I could not switch on the navigation bar by clicking on the icon. The icon is there, but when I click, the icon will be shown on the left side on the screen instead of the right side, but no navigation bar is visible. That means I don't have any navigation when I load such a project and need to kill Etoys and start again to be able to work. The problem occurs with projects which worked some time ago.
