Summary: MDI child frame and wxCheckListBox menu problem

Initial Comment:
I'm having a problem getting a wxMDIChildFrame derived class' menu to work. It seems that some problem occurs when Windows is trying to draw/measure the menu items due to an invalid handle.
15:53:49: ..\..\src\msw\dc.cpp(1758): 'GetTextExtentPoint32()' failed
with error 0x00000000 (the operation completed successfully.).
15:53:49: ..\..\src\msw\dc.cpp(1758): 'GetTextExtentPoint32()' failed
with error 0x00000006 (the handle is invalid.).
15:53:49: ..\..\src\msw\dc.cpp(1758): 'GetTextExtentPoint32()' failed
with error 0x00000006 (the handle is invalid.).

To reproduce the problem, add the last two lines to the
constructor of the mdi sample project like this;

MyChild::MyChild(wxMDIParentFrame *parent, const wxString& title)
      : wxMDIChildFrame(parent, wxID_ANY, title, wxDefaultPosition,
wxDefaultSize,
                        wxDEFAULT_FRAME_STYLE | wxNO_FULL_REPAINT_ON_RESIZE)
{
   canvas = (MyCanvas *) NULL;
   my_children.Append(this);

   // this should work for MDI frames as well as for normal ones
   SetSizeHints(100, 100);

   // this triggers the measuring and font creation
   wxCheckListBox *checkListBox = new wxCheckListBox(this, -1);
   checkListBox->Append(L"Test");
}

If you remove the Append() call, the menu will work as intended. At least this happends under Windows XP.

Unfortunately wxCheckListBox continues to have a bad effect on menu
drawing, bug 1713158 persists.
