I don't think I could do it if I meant to; it's not that I am holding directional keys when the interface switches which I could see as a potential cause. It occurs at random, I may have been on the galactic map for 5 minutes and it'll just happen. It must be keyboard related, it's only the arrow range of movement, it doesn't scroll in irregular directions. I have had it occur where it will scroll at a 45 degree angle and I have to hold 2 arrow buttons to compensate. James.
