I have multiple ResourceDictionaries together in a folder in my project and previously I used to use MergedDictionaries in my Window.Resources to bring them together into one dictionary. I then moved that merged dictionary to it's own file, and all of the styles and everything works exactly the same... except for the Menu control's background. Nothing has changed except the dictionary having its own file, and everything else works fine. I even have the dummy style added in there and the Menu's background still won't display. Any idea what could be wrong?
