Private Sub wndReportControl_SelectionChanged()
    Dim Row As ReportRow
    Dim a As Integer
    On Error Resume Next
    Debug.Print "Selection Changed. Focused Row = " & wndReportControl.FocusedRow.Index

    Me.Caption = wndReportControl.SelectedRows.Count & " row(s) selected"

    If (wndReportControl.SelectedRows.Count < 10) Then
        For Each Row In wndReportControl.SelectedRows
            Debug.Print "Selected: " & Row.Index
        Next
    End If

    If (wndReportControl.SelectedRows.Count = 10) Then
        a = 0
        For Each Row In wndReportControl.SelectedRows
            'Debug.Print "Selected: " & Row.Index
            a = a + 1
        Next
        MsgBox a
        'MsgBox wndReportControl.SelectedRows.Count
    End If

End Sub

Hi Mark,

I've found a "solution" for this problem !

Seems that if you set the focus to an other control (not the report control) the msgbox is shown without problem !

That's the reason why you don't have the problem with button's showing msgbox, the button got the focus before calling the msgbox !

Check my sample :

uploads/20090707_105826_VirtualList.rar

I've just added a simple textbox on the bottom of the screen.

Run the sample and (without doing anything else), go to menu "Report Control" / "Count selected".

You'll see 2 msgbox :

The fisrt is shown with the focus on report control (the report on background is empty --> Bug)
The second is show with the focus on the textbox (--> OK)

Don't know why but this may help you ?

At least you see the case when app call MsgBox itself by situation reached - no buttons and no user action involved but view is OK?!

And i repeat, there's also many others case in wich the report is cleared !

Not only by menu.

On the "form_queryunload" event, add a msgbox and you'll see the report is cleared !

I repeat - the problem is not in MsgBox - in VB Menu handling

try this function

Private Sub wndReportControl_SelectionChanged()
    Dim i As Long
    i = Me.wndReportControl.SelectedRows.Count
    If i = 10 Then MsgBox "SelectedRows.Count " & i
End Sub

and you will see picture:
