RT-GUI控件问题!

为什么在window中加入combobox后出现线程死机，没死机前，点击下拉会刷掉下拉框，无法选择下拉中的项。window是通过button打开的。同样的combobox放在view下没问题。

parent = RTGUI_TOPLEVEL(rtgui_widget_get_toplevel(widget));
	rtgui_rect_moveto(&rect, 130, 120);
	win = rtgui_win_create(parent, "无标题", &rect, RTGUI_WIN_STYLE_DEFAULT | RTGUI_WIN_STYLE_NO_TITLE );
            /* 创建一个确定按钮 */
	rect.x1 = 280;
	rect.x2 = rect.x1+60;
	rect.y1 = 310;
	rect.y2 = rect.y1+30;
	button = rtgui_button_create("确定");
	rtgui_widget_set_rect(RTGUI_WIDGET(button), &rect);
	rtgui_container_add_child(RTGUI_CONTAINER(win), RTGUI_WIDGET(button));
	rtgui_button_set_onbutton(button, window_close);
             /* 创建一个取消按钮 */
	rect.x1 +=70 ;
	rect.x2 = rect.x1+60;
	rect.y1 += 0;
	rect.y2 = rect.y1+30;

button = rtgui_button_create("取消");
	rtgui_widget_set_rect(RTGUI_WIDGET(button), &rect);
	rtgui_container_add_child(RTGUI_CONTAINER(win), RTGUI_WIDGET(button));
	rtgui_button_set_onbutton(button, window_close);

rect.x1 = 130;
	rect.x2 = rect.x1+400;
	rect.y1 = 120;
	rect.y2 = rect.y1 + 20;

label = rtgui_label_create("  请输入起始样本号/孔位");
    /* 设置标签位置信息 */
	rtgui_widget_set_rect(RTGUI_WIDGET(label), &rect);
    /* 添加标签到视图中 */
	rtgui_container_add_child(RTGUI_CONTAINER(win), RTGUI_WIDGET(label));

rect.x1 += 20;
	rect.y1 += 50;
            rect.x2 = rect.x1+80;
	rect.y2 = rect.y1 + 20;
            label = rtgui_label_create("起始样本号");
            rtgui_widget_set_rect(RTGUI_WIDGET(label), &rect);
    /* 添加标签到视图中 */
	rtgui_container_add_child(RTGUI_CONTAINER(win), RTGUI_WIDGET(label));

rect.x1 = 280;
	rect.y1 = 200 ;
            rect.x2 = rect.x1 + 80;
	rect.y2 = rect.y1 + 20;
	cbbox = rtgui_combobox_create(HoleStart_Line, sizeof(HoleStart_Line)/sizeof(HoleStart_Line[0]), &rect);
	rtgui_container_add_child(RTGUI_CONTAINER(win), RTGUI_WIDGET(cbbox));
/* 模态显示窗口 */
	rtgui_win_show(win, RT_TRUE);
	/* 采用模态显示窗口，关闭时不会自行删除窗口，需要主动删除窗口 */
	rtgui_win_destroy(win);
