At work I'm currently in the process of transferring quite a lot of 3D Data from one Database to a newer Database. In that process you can only save once you are fully done, which takes a couple hours.

What you then do is click 'Ok' and it does exactly what it says. It terminates the program and your day is ruined. Thanks Catia.
