If the last used deck cannot be loaded at startup, Wiz Solitaire will revert to the standard deck, after notifying the user.
This change will fix a freezing problem reported by some users when the game was first run from a mounted .dmg volume and later from the Applications folder.
On a side note, Wiz Solitaire is now listed on iusethis: if you've got an account there, please add it among your apps.
