window tile vertically and horizontally not workin

 

I use the codejock to reskin my old MFC 6.0 application. But, after reskin, the basic window function not working properly. If I open several windows, then want them tile vertically, but it is not working. the code is like the following:

 

 

void CCrossLogView::OnTileVertical()
{
       ((CMainFrame *)cwndFrame)->MDITile( MDITILE_VERTICAL );
}

 

CFrameWnd *             cwndFrame;

 

Any hints to resolve this problem?

 

Thanks
