Yes, but as was mentioned before it only works if you have the right
settings in the "general controls" control panel:-(

I'm working on a different hook for setting the folder for the
StandardFile calls, probably an extra optional argument that signifies 
the folder where you want to go. It's not simple, though, because
it'll have to use the event hook, and that's already used for other
things.

A good place to put this would be the interactive startup file, or, if 
you use the IDE, the scripts folder.

This is because the MacOS doesn't really have a working directory
concept. I keep noticing that various extensions also muck with
Python's idea of the working directory: Click there it is! is one of
them, and the valuefax receiver is another. There's unfortunately
little to do about this, short of completely ignoring MacOS's working
directory and keeping the working directory ourselves:-(

It's the return value of macfs.SetFolder().

What exactly do you solve here?
