After loading that version and executing:

   ed := SystemEditor new.
   (ed at: #SimpleButtonMorph) addInstVarName: #foo.
   ed commitWithProgress.

nothing at all happens, e.g., no variable gets added to 
SimpleButtonMorph (this is in 3.10.7159 in case it matters). The same 
for mtf.161 which I tried as well.

Is there something resembling a "stable" version of SystemEditor that I 
can use to try some of the harder tasks on? The experience so far is a 
bit unsatisfying given that SE doesn't execute basic tasks correctly.
