I'm not sure that this is a bug, but, as I was culling an object list, I opened Image Manager so I could delete images as I deleted the objects from the list. When the plan window was in front, I went up to Window in the main menu to choose the Image Manager, but it was not on the list. I then clicked Image Manager under Image, and it appeared just as I had left it, i.e. open to NGC objects.

By the way, I just found that the same is true for the Bug Report window. Maybe these are special windows that will not show up on the Window list?

Fixed. Plus a whole lot of other "neglected" windows.
