I have a 100% reproducible crash in Starry Night V7. If open the equipment list window (Edit->Edit Equipment List) then select an item like an eyepiece or a telescope and delete that item then press delete again before selecting another item from the list SN7 will crash.
Also when an item is added to this list in the window the FOV sidebar does not update (all the items disappear). These do return if you go out of the FOV sidebar and then back in again.
I am running SN7 under Windows 8.1.
