Do you have the same with 30?
Because I know that there were some problems when we merged OC and EC but this is nearly more than a year ago.

Nicolas this is probably not gratuitoulsy and you know it. Doing imply doing mistakes. Give me a fully tested system and you will see that we
will not break it.
So can you open a bug entry so that we do not forget to fix it.

Thanks this is the best things to do.
You see probably one guy tried to speed up the system and this happens.

We are constantly using Pharo alpha the complete moose and pharo

I guess so. Esteban does not look like using Pharo2.0 but I will let him reply.

Us too. :)
Thanks for reporting problems. Can you open bug entries so that we can handle these problems?
