Apologies, sorry for screaming.

When I try to load an older .morph (Squeak 3.8) it seems to work fine. I
think my problem is there were some .st files I didn't have loaded before
trying to load the 4.3 morph.

Plea still stands, however: Please do not even THINK ABOUT changing the
format of .morph without giving us a way to convert.
