Hi Chris -- I was hoping you might help. I was trying to create a  
MagmaRepositoryController using the following code ( from the example  
on the wiki ) after installing version 144 loaded off monticello. It  
used to work using version 125 so not sure what happened. Also get  
walkback trying to open session. ( yes -- using mac ).

MagmaRepositoryController create:  
'/Users/brendamoffitt/Desktop/Larry/Squeak/Squeak3.7/ 
myRepository.magma' root: ( Dictionary new ).
Thanks in advance --
Steve
