编码的UI正在识别控件，但未执行任何操作

Question

我写了下面的代码，

       WinWindow w = new WinWindow();
       w.SearchProperties[WinWindow.PropertyNames.Name] = "Card Action";
        w.SearchProperties[WinWindow.PropertyNames.ClassName] = "#32770";
        w.SearchProperties[WinButton.PropertyNames.ControlType] = "Window";

        WinWindow w2 = new WinWindow(w);
        w2.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
        w2.SearchConfigurations.Add(SearchConfiguration.VisibleOnly);
        w2.SearchProperties[WinWindow.PropertyNames.ControlType]="Window";
        w2.SearchProperties[WinWindow.PropertyNames.Name] = "Insert Card";
        w2.SearchProperties[WinWindow.PropertyNames.ControlId] = "2032";

        WinButton b1 = new WinButton(w2);
        b1.SearchConfigurations.Add(SearchConfiguration.AlwaysSearch);
        b1.SearchConfigurations.Add(SearchConfiguration.VisibleOnly);

        b1.SearchProperties[WinButton.PropertyNames.ControlType] = "Button";
        b1.SearchProperties[WinButton.PropertyNames.ClassName] = "Button";
        b1.SearchProperties[WinButton.PropertyNames.Name] = "Insert Card";
        b1.DrawHighlight();
        Mouse.Click(b1);

它已识别控件，但无法执行点击操作。

错误： 测试方法CodedUITestMethod1抛出异常： 另一个控件正在阻止该控件。请使被阻止的控件可见，然后重试该操作。其他详细信息：TechnologyName：'MSAA'名称：'Insert Card'类名：'Button'控件类型：'Window'
