I have the problem that the menues somehow go away, when the focus goes to my dynamically loaded UserControl associated with a ContentControl.
The area below the Fluent stuff (Application area) is covered with a grid which is conteining a ContentControl.
If I put some stuff in that ContentControl (a rather complex page with datagrids etc.) the DropDown Buttons inside the RibbonGroupBox are going away. After selecting the tab again they will be back again. Very strange...
Another strange thing is - under Win 7 with Aeoro the second tab is completely transparent. And therefore not really visible. Did I miss some styling here?
