Window Control Buttons "Black Out" when Window is maximized

Mar 16, 2010 at 2:48 PM


I am building my first ever WPF application and also using the RibbonControlLibrary for the first time.  So far everything works well except for the following:

When I maximize the RibbonWindow at run-time the Close, Restore and Minimize buttons black out and assume the same colour as the application title bar.  If you hover the mouse where they should be, you actually get their respective mouse-over tooltips and you can click them, but it is not ideal to have users hunt for where to click to use those controls.

The application is very simple.  It is a RibbonControlWindow and a Grid control containing a DataGrid.

If anyone has seen this before and can offer some insight, I will appreciate it tremendously.  I would be happy to poat the xaml on request.  Someone recommend I use a visual debugging tool like Snoop, but it is not picking up my application.

Kind regards

Ah, seems like a known issue.

Does anyone know if there is a later version where this is fixed yet?
