System button dblclick not working on MDIChild

Our app is an MDI app. It's 'different' than traditional MDI apps in that we add a ribbon bar and System button to the child windows since each window presents the User with a unique set of 'tools' on the ribbon bar.

 

Double clicking on the System button in the MIDParent works correctly, shutting down the app. But double clicking on the System button of the child windows no longer fires the shutdown event. In 10.4.1 this worked.

 

Is there a workaround or a flag I'm not setting?

 

Thanks again for a great product and great support!

I catch the cbTitle_Execute event (cbTitle si the ribbon bar that has the large round System button) but it does not catch a double click. It catches the events for the button items I've added ('Save', 'Save and Close' and 'Discard and Close' in my case) but not a double click.

 

Here's how I create the ribbon bar and System button:

... in form load...

    ConfigureMdiChildEditorRibbonBar cmdbars.AddRibbonBar("Title"), bShowRibbonBarQuickAccess

...

 

Private Sub ConfigureMdiChildEditorRibbonBar( _
    ByVal rb As XtremeCommandBars.RibbonBar, _
    ByVal bShowQuickAccess _
)
    With rb
        .AllowMinimize = True
        .EnableDocking XtremeCommandBars.XTPToolBarFlags.xtpFlagStretched
        .ShowCaptionAlways = False
        .ShowGripper = False
        .MinimumVisibleWidth = 100
        .ShowQuickAccess = bShowQuickAccess
       
        AddMdiChildEditorSystemButton rb
   
        .EnableFrameTheme
        .RedrawBar
    End With
End Sub

Private Sub AddMdiChildEditorSystemButton(ByVal rb As XtremeCommandBars.RibbonBar)
    Dim cbp As XtremeCommandBars.CommandBarPopup
   
    Set cbp = rb.AddSystemButton()
    With cbp
        .CommandBar.SetIconSize 32, 32
        .IconId = ID_TRYGEAR_ICON
        .flags = xtpFlagNoMovable
    End With
    AddMdiChildEditorSystemButtonButtons cbp
End Sub

 

' Caller must add BTN_ID_SAVE, BTN_ID_SAVE_AND_CLOSE, and BTN_ID_DISCARD_AND_CLOSE
' to CommandBars' Execute() handler
Private Sub AddMdiChildEditorSystemButtonButtons(ByVal cbp As XtremeCommandBars.CommandBarPopup)
    AddSystemButtonButton(cbp, BTN_ID_SAVE, ICON_SAVE, "Save").Enabled = CanSaveObjects()
    AddSystemButtonButton(cbp, BTN_ID_SAVE_AND_CLOSE, ICON_SAVE_AND_CLOSE, "Save and Close").Enabled = CanSaveObjects()
    AddSystemButtonButton cbp, BTN_ID_DISCARD_AND_CLOSE, ICON_DISCARD_AND_CLOSE, "Discard and Close"
End Sub

Heres my ribbon bar event code:

Private Sub cbTitle_Execute(ByVal Control As XtremeCommandBars.ICommandBarControl)
    Select Case Control.id
    Case BTN_ID_SAVE, BTN_ID_SAVE_AND_CLOSE, BTN_ID_DISCARD_AND_CLOSE
        HandleFileOps Control.id
    End Select
End Sub

Sorry for the confusion.
