[Squeakland] Problems loading old projects

[Karl]

I have run across a few issues loading some old projects. The project 
loading had problems with the encoding, that was quite easy to fix. But 
and other issue is that the font's in the image have changed since the 
project were made. Upon loading the font's are replaced by the images 
default eToy font and that screws up the layout of all scripts. Is there 
a way to relayout all the scripts or
do I have to do this manually by making new scripts ?
