[0.7.1] right click on empty drill shows a small gray box

[LoSboccacc]

If you open an electric drill with the right click, like to insert/remove addon,
and the drill is on no resources,
a small grey box appears on the top left corner

I can verify this bug, already happening in 7.0. The grey box is the background for the ressource. If there's no ressource, the box will get moved to the top left corner.

Hello, thank you for the report, fixed for 0.7.3
