There are some historic raisins on why the plugin creator engine doesn't listen to those close events to terminate the instance.

Thanks. I've read through that thread carefully and have changed my Qt.quit() lines as follows:
Is this safer? Will it cause any problems, e.g. leaving garbage behind?
It looks as though I can just leave the red X button alone — since the dialogue closes as required, (in which case my Close button is redundant.)

All enabled Plugins are instantiated at the moment of enabling them (which usually is when MuseScore launches) and are cleaned up when the Plugin Engine quits (which is at a Qt.quit() call or at program end).
