I've had no difficulty doing this with version 6 and version 7
on my Mac. Previously, I had done that with version 5 and
version 6. For the case of version 5 and 6, I modified the
init.m file in the Kernel directory to detect which version was
being launched and load different things accordingly. For
example, I had a function defined to return the path for the
working notebook automatically loaded in version 5 which is
replaced by NotebookDirectory in version 6 and 7.
