Bug/glitch/problem: Arrow keys not working

[Twi]

I keep running into this problem where the arrow keys in ShipMaker stop working and I can't scroll. Bit of a handicap if one is making very large ships.

I thought I could fix this by clicking a 'name' box on a weapon, since it seemed to earlier, but it does not seem to be the case now.

Why does this happen and how do I fix/prevent it?

Click on any of the number fields on a weapon or the likes and press enter. That should do the trick. This problem mostly comes up when you edit one of the number fields and then don't press enter afterwards.
