xtang先生：
您好！
Photon microGUI 的Working with Code 一章里面有这样一句话，我不知怎样理解，特向你请教！
If you have more than one instance of a window module displayed at a time, then you’ll have a problem accessing the widgets in the window. The problem stems from the fact that ABW_instance_name for any widget in a window module points to the last created instance of the widget.
