Right click on object that has details bring up unclosable window.

[Former user]

Any in-game object that would bring up a detail window does so BUT the [x] will not close the window.

Right mouse click on any object that can bring up a detail window (screenshot has iron candleabra) and then attempt to close detail window with the [x].

I can’t reproduce this. Which platform do you play on?

Can you move the window by dragging it around? Can your right click the window so that it will close?
