Spaceball Oddities

 From:  DannyT (DANTAS)
Hi All,
I use a Spaceball, I had a look on the forum but nothing with this problem.
On some particular models every direction works except for twist, but the funny thing is when I open a new session and draw a box it's all good.
I think I've worked out the logic behind the rotation point focus in MoI, but on this one particular model it won't twist, has anyone else experienced this, it's starting to get annoying.
