Conflict between "fix rigid..." and "velocity set ..."!

Dear axel and steve,

I would appreciate if you send a comment on this issue.
The strange thing about the problem is that if I put the commands in a just one run stage (as below), the “velocity set … command” works and the rigid group moves!!!
It seems there is a bug in LAMMPS.

But I don’t appreciate, that you don’t follow the detailed advice that I have given you in a personal email already.

So I have no more comments left. Perhaps someone else has more frustration tolerance than me.

There is no convincing proof for that here.
