Ok, it seems I've got a lot of problems tonight.

I created a simple rigid body simulation. One active and one passive one gravity field afecting active. But I want to start the simulation at frame 60 not 1. When I keyframe active under rigid body and set it to 0 at frame 59 and 1 at 60 nothing seems to happen. my object does not fall.
There is nothing wrong wit the rigid bodies, since when I remove the keys and start the simulation from frame 1 it works fine.
How can I get this to work, any ideas

thanks
