Re: Possible bug, or I am doing something wrong?

by the way, it works fine of the only thing I change is the 

"\relative c''" of the "up" staff, to 
"\relative c'" or lower. 

The whole thing crumbles only when the 

"\relative" 

of the upper hand goes from c'' and up.

Otherwise, it works as intended. Even without entering voices.
