When you drag-n-drop a multi scene file (e.g. LIF), two widgets pop up.
The top one lets you choose to clear layers or unpack channels via checkboxes.
The bottom lets you choose scenes.
If you close the top one as spurious (whether you check something or not) and then try to load a scene, you get a key error:
KeyError: 'AICSImageIO Scene Management'

Expected Behavior
There should be no error. If the checkbox widget is closed then the defaults (unchecked) should be used.
Alternately—or perhaps better yet?—the widget should have an 'Apply' button to set the settings and let the widget be closed.
