>The MainWindow class is derived from mmBaseWindow and the mmBusinessWindow or mmBusinessmaintWindow are derived from mmBaseWindow too. So, the only thing you should do is to derive your MainWindow from the mmBusinessWindow class in the MainWindow.xaml.cs file. Just change mmBaseWindow to mmBusinessWindow.
