'Stuck' keys - win message handler

EDIT: sorry, the title was a bit misleading, so i changed it I'm writing a camera class, and have it all working, except for one issue. When i'm strafing or walking everything is ok, and using mouselook is ok too. But if i say walk and mouselook for a while, and let go of the arrow (or W) key, the camera keeps moving for a while (same for strafe etc), and mouselook still works at this stage. I set a breakpoint on WM_KEYUP and that breaks a while after releasing the key. I'm guessing the camera rotation code is blocking things up, but can it really block the message loop? I'm running on a slow machine, but i've looked at some stuff from game tutorials, and the message handling there is pretty much the same, and that code doesn't suffer from "stuck keys" like mine. i've pasted how i handle keys etc below in the main loop

while(1)
  {
    if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) 
    { 
      if(msg.message == WM_QUIT)					// If the message wasnt to quit

        break;
      TranslateMessage(&msg);						// Find out what the message does

      DispatchMessage(&msg);						// Execute the message

    }

    key_handler ();

    player_cam.set_view_by_mouse ();

    glLoadIdentity();

    gluLookAt (player_cam.m_position.m_x, player_cam.m_position.m_y, player_cam.m_position.m_z,
               player_cam.m_forward.m_x, player_cam.m_forward.m_y, player_cam.m_forward.m_z,
               player_cam.m_up.m_x, player_cam.m_up.m_y, player_cam.m_up.m_z);
    
    //Do rendering here....

    render_scene ();
  }

key_handler looks like this:
   
if( (GetKeyState(VK_UP) & 0x80) || (GetKeyState('W') & 0x80) ) 
  {
    player_cam.move (0.1f);
  }

  if( (GetKeyState(VK_DOWN) & 0x80) || (GetKeyState('S') & 0x80) ) 
  {
    player_cam.move (-0.1f);
  }

  if( (GetKeyState(VK_LEFT) & 0x80) || (GetKeyState('A') & 0x80) ) 
  {
    player_cam.strafe (-0.1f);
  }

  if( (GetKeyState(VK_RIGHT) & 0x80) || (GetKeyState('D') & 0x80) ) 
  {
    player_cam.strafe (0.1f);
  }

and my winProc looks like this
   
   
LRESULT CALLBACK WinProc(HWND hWnd,UINT uMsg, WPARAM wParam, LPARAM lParam)
{
  if(first_window.get_hwnd() != NULL)
  {
    //Plugin the window message handler

    return (first_window.message_handler (uMsg, wParam, lParam));
  }
  else
  {
    first_window.set_hwnd(hWnd);
    return (DefWindowProc(hWnd, uMsg, wParam, lParam));
  }
}

where first_window is a class that creates the window and sets up the OpenGL stuff... and has this message handler
      
LONG    lRet = 0; 
  PAINTSTRUCT    ps;

  switch (uMsg)
	{ 
    case WM_SIZE:										// If the window is resized

      if(!m_fullscreen)								// Do this is we are not in full screen

	  	{
        m_width = LOWORD(lParam);
        m_height = HIWORD(lParam);
			  size_openGL_screen();// LoWord=Width, HiWord=Height

  			GetClientRect(m_hwnd, &m_rect);					// Get the window rectangle

	  	}
      break; 
 
	case WM_PAINT:										// If we need to repaint the scene

		BeginPaint(m_hwnd, &ps);							// Init the paint struct		

		EndPaint(m_hwnd, &ps);							// EndPaint, Clean up

		break;

  case WM_DISPLAYCHANGE:
    break;

    switch (wParam)
    {
      case VK_ESCAPE:								// If we hit the escape key

        PostQuitMessage(0);						// Send a QUIT message to the window

        break;

      case VK_F1:
        set_fullscreen (!m_fullscreen);
        break;

		}
		break;

    case WM_CLOSE:										// If the window is being closes

        PostQuitMessage(0);								// Send a QUIT Message to the window

        break; 
     
    default:											// Return by default

        lRet = DefWindowProc (m_hwnd, uMsg, wParam, lParam); 
        break; 
    } 
 
    return lRet;

any help appreciated.. Thanks in advance [edited by - jhavna on July 23, 2003 10:11:20 AM] [edited by - jhavna on July 23, 2003 10:11:55 AM] [edited by - jhavna on July 23, 2003 10:13:22 AM] [edited by - jhavna on July 23, 2003 11:37:31 AM]
