[chimera-dev] chimera.widgets.ModelOptionMenu aggressiveness

I am using chimera.widgets.ModelOptionMenu in my plugin as suggested, but when I attempt to save a screen image its as if my plugin/the structure is being unmapped then mapped again. The tiles are rendered before my plugin reloads the interface. Is there a way I can programmatically destroy my plugin's instance so I can at least take a screenshot without anything changing? I poked around chimera.extension.manager without success. Thanks, Charlie
