Icon packager system shutdown question

I downloaded and installed Iconpackager. Works great, except for one thing: whenever I shut down and re-start, the changed icons on my desktop are still there, but when I go into "my computer" all the icons are back to the windows default. Things like my folder icons, printer, control panel- everything is how it was. Is this mornal? It only takes a moment to reapply the new set of icons, but shouldn't they remain even after a shutdown/restart? I can't imagine the thing is set up so that you have to reset the icons everytime you start your system. Thanks...
