I just installed C6 today.  I wanted to wait with the expectation that there would be bugs that would hopefully be worked out.

Immediately out of the box (figuratively), I notice that when I duplicate and object and then edit it (model or shader), I cannot create a new master (using the attached image of the dialogue box).

This is very annoying for a couple of reasons.

1.)  I have to have the ability to create new masters off of old ones.  Without it, I will go back to C5 and not touch C6 again.

2.)  Such a bummer to find the new version doesn't work after only using it for 20 minutes.

Any help would be had.

Thanks,
