  Ok.  Do you have the correct EtoysV3.sources file, yes?

  - Is it really after you save the image and relaunch it?  FileDirectory
    class>>startUp won't have any effect until you manually execute it
    or restart the image.

  - Do you have write permission to the directory?

And the biggest question is:

  - *Why* do you want to change the default directory in that way, not
     just copying the .image and .changes file to the directory?

  Let us solve one problem at a time.  So please explain the reasoning
behind of the change first place.  Without chainging the #startUp
method but just open a workspace, does your image freeze?

  Accepting a workspace has an obscure effect but you usually don't
have to care it at all.

  Did you actually evaluate these expressions to play the sound?  What
is your VM and what is your platform?  Does your system have the
proper sound system and Squeak VM is using a right driver?  At some
old time, Unix VM did freeze the image when trying to play a sound and
when the sound driver wasn't available.

  But you did change a crucial method, yes?

  I tried to change the startUp method on my computer and it doesn't
freeze my image (as it shouldn't) there is still something missing.
Hope you explain it in a way that somebody else can reproduce...
