EnumEditBox Focus Problem

I have an application that uses a TabbedMdiContainer with two Document Windows. One window contains a WPF DataGrid and the other contains the WinForms SyntaxEditor. If I double click a cell in the DataGrid that contains an EnumEditBox (whose enum doesn't use Flags) and then click inside the syntax editor, the DG cell edit ends, as expected. However, if I double click a DataGridCell that contains an EnumEditBox (whose enum uses Flags) and then click inside the syntax editor (so it gets focus), the DG cell remains in edit mode.

Is there anything I can do so an EnumEditBox (whose Enum has Flags) will have the same focus behavior as an EnumEditBox (whose Enum doesn't use Flags)?

BTW, I'm sending a sample application over that reproduces the issue.

Thanks,
