I have a little question,��

I need to run a piece of code from the command line, if I do the following in Mac it works

./Pharo --headless ../Resources/Pharo3.0.image eval '3+3'

I see the result of the evaluation in the console, but if I do the same in Windows it runs but it doesn't show the result in the console.

Any clue of why this is happening? And how to solve it?

Thanks!
