I want to share you a technique about how to Show a MDIChild or alternate between them with no Flicker.

try

SendMessage(Application.MainForm.ClientHandle, WM_SETREDRAW, 0, 0);

Show;

finally

SendMessage(Application.MainForm.ClientHandle, WM_SETREDRAW, 1, 0);

RedrawWindow(Application.MainForm.ClientHandle, nil, 0, RDW_ERASE or RDW_FRAME or RDW_INVALIDATE or RDW_ALLCHILDREN or RDW_NOINTERNALPAINT);

end;

Enjoy it!!! It works very well.
