In this vertion ,we restruct the display ;

//2006/12/01
In function DispProc,case MSG_SHOWIMG is overlapped
with case WM_PAINT; As aresult of which,we delete the latter while remain the other;

wile WM_PAINT is sent by updatawindow,we delete it,too;and MSG_SHOWIMG is sent by sentmessage;

From the beginning and up to now,the displaying just 
can't satisfy us, we need to know what's the hell 
are the bullshit doing and refresh the screen;
To meet the requrement,we place the sentmessage at 
every beginning of subframe dispress to refresh,at the same time,we will know what's going on;

To do more,we add some text on the window's title;
