Enable 2007 Frame Problem

I am enabling the Office 2007 frame theme for our app.  It works well at first, but pretty quickly you start to see the standard windows controls (Minimize, Maximize, etc) being displayed on top of the "themed" control box.  Problem stops for a minute if you minimize, then maximize the form, but always starts again.

 

Same problem does not happen when I'm running the CJ ribbonbar sample.

 

Here's the code I'm using:

 

With CommandBar1
        .VisualTheme = xtpThemeRibbon
        .EnableOffice2007Frame True
        .Options.SetIconSize True, 32, 32
        .ActiveMenuBar.EnableDocking xtpFlagStretched
        .Icons = frmMain.ImageManager2.Icons
        .Options.UseDisabledIcons = True
        .Options.IconsWithShadow = True
        .Options.OfficeStyleDisabledIcons = True
    End With
   
    Set RibbonBar = CommandBar1.AddRibbonBar("The Ribbon")
    RibbonBar.EnableDocking xtpFlagStretched
    RibbonBar.EnableFrameTheme
    RibbonBar.Closeable = False
    RibbonBar.Customizable = False
   
    Set ControlFile2 = RibbonBar.AddSystemButton()
    ControlFile2.IconId = 3000
    RibbonBar.ShowQuickAccess = False
   
    Set RibbonBar = frmMain.cbMain.ActiveMenuBar

 

Can anyone see a problem here?

 

Thanks,

 

Dan
