I am trying to change the application theme at runtime using the approach provided on the Rad Controls for WPF website.

I'm clearing the default MergedDictionaries instantiated in App.xaml and updating with new MergedDictionaries from the NoXaml binaries that I have referenced in the project.  The button to execute this code is located on the Backstage via DelegateCommand.  When the code is executed, it appears to affect the rest of the application but not the Backstage itself.  If I navigate to a different ribbon tab and back to the Backstage, then much of the styling is updated, but with the loss of the hover effects and some of the styling of the strips on the left hand side.
I have references to Telerik.Windows.Controls.xaml, Telerik.Windows.Controls.Input.xaml, Telerik.Windows.Controls.Navigation.xaml, and Telerik.Windows.Controls.RibbonView.xaml being updated when the code runs.

Is there something that I should be doing differently?  Thanks for your help! 

Hi Alan,

Thank you for bringing this issue to our attention. I investigated it and I can confirm that this is a bug. I logged it in our PITS, where you can track its progress. We will do our best to fix this bug for the incoming Service Pack, which should be released in the end of this month.

Regards,
Stefan
