I'm trying to create a MainFrame that is composed of a SplitterWnd, the left side of which is a ShortcutBar and the right side, a normal childframe - in this case a view that itself keeps track of multiple views of the same document using it's own tab manager.  I want the MainFrame to also have a tab manager, such that it keeps track of all open documents.  I had this latter part (the two levels of tab managers) working well, until I added the SplitterWnd.  I can get the ShortcutBart to appear, but the right side always remains empty and the MainFrame tabs per document seem to have disappeared.  I'm sure it has to do with the layering, but I can't figure out what I'm missing to get this to work.  Why do the tabs disappear and the views no longer populate the clientframe area?
