Re: Package won't load after v.7 upgrade

Hi,

As a general rule you **never** want to put your applications within
the Mathematica.app directory.  This modifies your Mathematica
application itself and, when you upgrade your Mathematica version
everything that you place there will be removed.  Rather you want to
put it in:

ToFileName[{$UserAddOnsDirectory, "Applications"}]

This directory is persistent through upgrades to Mathematica and is
always contained in $Path.

I hope thei helps.
