Ok, I'm having some very odd stuff going on with mates in SW2006 Sp2.1. I go to make one component, and another moves, despite the fact that it's fixed with other mates and has in context stuff relating to it, which then all updtaes as though it were ok for that part to move... I know I'm not being very clear, it's a very strange thing that's going on - anyone else seeing messed up mates in SW2006 SP2.1
