Re: [AD] winXP ALT+key beep problem.

[AJ <aj@xxxxxxxxxx>]

the URL

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/userinput/keyboardaccelerators/keyboardacceleratorreference/keyboardacceleratormessages/wm_menuchar.asp

documents the WM_MENUCHAR  allegro is sent when the user presses the 
ALT+key.

from the MSDN doc, it says if we return  MNC_CLOSE  in the hi word and 
the key in the lower word, it will not issue the beep.

i added this to the /allegro4.1.18/src/win/wwnd.c
func  directx_wnd_proc()
case WM_MENUCHAR :
	return (MNC_CLOSE<<16)|(wparam&0xffff);

which prevents the beep.
