Hi Clément,

the earliest vm I can run on Windows(!) is 2.7

For this, I grab the windows vm, image, changes ... from
http://ftp.squeak.org/2.7/
Start the vm,
resize the display to make it smaller,
make a snaptshot with a new name 'small.image'
Now I reopen the original image and I can now load the
InterpreterSimulatorLSB with that smaller image:

(InterpreterSimulatorLSB new openOn: 'small.image') test
