Hi Bruno,

> Are you using CFTTest by the way?

No I am not using CFTTest. But I am using CohesiveFrictionalContactLaw 
with an old revision. Sometimes, I test the last revision to see how 
things have changed. And when I find a bug, I report it. This is the 
less I can do. So don't worry, I can wait ;-)
BTW, thanks to all yade developpers for your great job.

Cheers, Franck
