Since browsers prohibit it, I'm going to leave it. It's no big deal. Thanks!

Sorry, there's no universal browser-only solution for this. The browser security model explicitly prohibits access to local client's clipboard (though some browsers, like Netscape, have ways around that).
Using a non-browser code (like flash or similar methods) is the only way to do it in a cross-browser implementation.
