在STemWin程序中，delay_ms()函数不起延时作用是啥原因？

static void _DashboardDemo(void) {
WM_HWIN       hClient;
WM_HWIN       hWin;
WM_HWIN       hButton2;
_Break = 0;
_Break2 = 0;

//
  // Use memory devices
  //
  WM_SetCreateFlags(WM_CF_MEMDEV);
  WM_EnableMemdev(WM_HBKWIN);
  //
  // Set callback for background
  //
  WM_SetCallback(WM_HBKWIN, &_cbBkWindow);

//
  // Create backgrund
  //
  _CreateBackGround();

hClient = WM_GetClientWindow(WM_HBKWIN);//取客户区句柄
hWin = GUI_CreateDialogBox(_aDialogColor,GUI_COUNTOF(_aDialogColor), &_cbDialogColor, WM_HBKWIN, 0, 0);
  hButton2 = _CreateButton(170, 180, 120, 50, 5, 25, "Cancel" , 0 , GUI_ID_BUTTON2);

//
  // Handle the demo
  //
  GUI_CURSOR_Show();

do{
GUI_Exec(); //or GUI_Delay();
LED0=1;
LED1=0;
//GUI_Delay(200);
delay_ms(300);
LED0=!LED0;
LED1=!LED1;
delay_ms(300);
//GUI_Delay(200);
  }while(!_Break2);

//
  // Unset callback
  //
  WM_SetCallback(WM_HBKWIN, NULL);
  //
  // Clear memory
  //
WM_DeleteWindow(hWin);
WM_DeleteWindow(hButton2);
}
循环中的2个delay_ms(300)函数好象根本不延时，造成两个LED常亮不闪，啥原因啊？换成GUI_Delay(200)语句后，LED灯闪烁正常，谢
(程序是在原子战舰板的“跑马灯实验（库函数版）”工程的基础上移植STemWin2.8运行正确后，再修改的，无OS。)
