In this video I clicked the minimize button about 7 times before it actually registered the press.
It seems to be easiest to reproduce when first having the focus on another window and then trying to minimize Orion.
Not only should it work in one click, but it aslo shouldn't take the focus away from the current window. For example, when minimizing other types of windows like Finder I am able to minimize it without ever leaving focus on another window. See video:
