I have a similar problem: when flying, my CTRL-UP precision direction control doesn;t work, it does nothing. The other three directions, LEFT, RIGHT, DOWN, with or without CTRL, work as advertised, as well as the uncontrolled UP key. This gives me major headaches whenever I encounter pirates. I die a thousand deaths each time I try to take them out. Can't get a bead on them to return fire. Any clues as to where I should look for a solution?
I cannot reproduce this. What keys are you using as up/down/left/right controls? Are you using joystick and keyboard together by any chance? Does it happen also without any OXPs installed (you can try starting a game in strict mode to test this)?
I'm using the arrow keys on my keyboard, and binary: Oolite development version 220.127.116.1160-160130-10ca9e2 (x86-64 test release) under Linux 3.19.0-61-generic
I used not to have this problem in previous versions I used, and only a few OXPs have been upgraded since I started playing again two months ago.
Just now tested the binary with only the following OXPs:
Same problem exists.
