If you have a Good and Happy version of vfs.cfg, then psclient.app should open on a double-click. I promise that a Good and Happy version will be included in the soon-to-be available new full download, or can be found linked to in several threads.
If you do have a Good and Happy version of vfs.cfg in the same folder as psclient.app and it still doesn\'t double-click-open, then I\'d be interested in seeing what Console.app has to say about the situation
Oooh, just thought of something. The updater has recently been trashing \"executable\" bits on psclient and updater, try executing the command \"chmod 755 psclient.app/Contents/MacOS/psclient\" and \"chmod 755 updater.app/Contents/MacOS/updater\"
If that fails, fill me in with Teh Details (tm)
