I have code that sets up my ribbon at runtime, and when an MDI child form closes or another tab is switched to, various root tools are hidden via rootTool.SharedPros.Visible = false.  That hides the tool everywhere (i.e. QAT, app menu etc.) and life is good.

However I recently added code to invoked SaveToBinary() and LoadFromBinary().  At first I had some exceptions loading b/c tools I was creating programatically already existed.  I worked around that w/various key existinence checking etc.

The problem I have now is that if the ribbon was loaded from the file, when I close a form and rootTool.SharedProps.Visible gets set to False, the tool remains on the QAT and the app menu.  I cannot figure out the difference so far but removing the LoadFromBinary call resolves the problem.

Any ideas?  I can change ribbon initialization code if needed to account for loading from a file but am unsure what if anything might need adjusting. If I have to I can manually persist and load select ribbon settings to disk but would prefer to avoid if possible.
