The Win32 documentation for ShowWindow says that SW_SHOWNORMAL is to be used 
when an app displays the window for the first time. SW_RESTORE is to be used 
when an app restores a minimized window. Since SW_RESTORE is #defined as 9, and 
SW_SHOWNORMAL is 1, I guess that Windows distinguishes between the two in some 
subtle way. 

MFC uses this for its frame windows:

                if (!IsWindowVisible())
                        nCmdShow = SW_SHOWNORMAL;
                else if (IsIconic())
                        nCmdShow = SW_RESTORE;
