2.57 Particle collision working?

I tried to use collision for particles and the particles just pass right through the plane. 2.56 works fine. Couple of days ago tried to use fracture tools and was told there was an error and was pointed to the updated files to download, is there a similar problem with the particle system? Or have they changed the work flow so drastically it doesn’t resemble what you do in 2.56? I downloaded the latest build from graphicall.org just to be sure, same problem.

I’ve been having the same problem with hair particles… I thought it had to do with a conflict between the hair dynamics and the particle dynamics. Unfortunately, I still don’t have a solution…
