I view a robot (opens a window on the right side). Then I view one of it's parts (opens a second window in the middle of my screen). Then, when I want to close that second window via a right-click, it can instead bring up info for a wall or whatever else is at my cursor but HIDDEN by said window.
(See the pictures.)
I want the second window to close, and the first window to remain unchanged. What happens is the second window remains unchanged and the first window now shows wall's stats.
