Apparently changing the window scrollbars in the middle of a window deferred repositioning operation is not allowed and confuses EndDeferWindowPos() which doesn't update the position of _grand_ children correctly in this case. This bug notably manifested itself when loading a wxScrolledWindow containing wxStaticBox from XRC, as the parent window was initially created with the default small size and then relaid out when it was resized to its real size on first wxEVT_SIZE event which also updated the scrollbars. As a result, the children of the wxStaticBox were shifted downwards. The fix simply flushes the current repositioning operation and starts one anew in wxWindow::SetScrollbar().
