Water Simulation

I have not been doing blender to long but have been playing with some of the new features and I have not been able to get a moving object to interact with the water sim. Is there some way of doing this or is that not possible with this version of the sim?

Have you tried setting the object as an obstacle in the fluid simulation tab?

Moving obstacles are not available in 2.41, but they should be coming up soon.

Just use CVS, moving obstacules and a lot more is available and it´s perfectly stable now
