Docking pane tabs not updated

I'm using XTP v9.51 and have several panes that are attached to each other, and the tabs are on the bottom.  When I load a file in one pane, I call SetTitle for that pane to update its title bar.  The problem is that the string for the tab isn't updated until I click on another tab.  To get around this, I call the pane manager's RedrawPanes function.

 m_pMyPane->SetTitle(szTitle);
m_paneManager.RedrawPanes();

In this function's class header file, I have the vars defined as:

 CXTPDockingPaneManager m_paneManager;

 CXTPDockingPane* m_pMyPane;

Am I managing panes incorrectly, or is this a bug in XTP?

FindPane() will return a CXTPDockingPane*, and then I can call the class function RedrawPane().  I've tried this and it doesn't update my tab string.

It works with RedrawPanes().  My thoughts are that the tab strings should be updated when SetTitle() is called, since the string in the pane's title is also the string in the tab.

I haven't stepped through the functions called in RedrawPanes().  Does calling this cause the object in each pane to be redrawn, or just the title bar and tabs?
