This little testapp:

        .386

        .MODEL FLAT,stdcall

        option casemap:none



        include \masm32\include\windows.inc

        include \masm32\include\kernel32.inc



        .CODE



main    proc c public



local   hConsole:dword

local   dwChar:dword

local   dwRead:dword

local   oldmode:dword



        invoke  GetStdHandle, STD_INPUT_HANDLE

        mov     hConsole,eax



        invoke  GetConsoleMode, hConsole, addr oldmode



        invoke  SetConsoleMode, hConsole, 0

@@:

        invoke  ReadConsole,hConsole,addr dwChar,1,addr dwRead,0

        mov     al,byte ptr dwChar

        cmp     al,1Bh

        jnz     @B



        invoke  SetConsoleMode, hConsole, oldmode



        xor     eax,eax

        ret

main    endp



mainCRTStartup proc stdcall

        invoke  main

        invoke  ExitProcess,eax

mainCRTStartup endp





        END

works as expected in Win9x (waits for ESC key pressed), but fails on WinXP (never ends because you dont get the ESC keys).

I want to know if theres a bug in the code above or in Win9x or is this a "feature" of WinXP?
