Collectible Card Game Headquarters

Whenever I go to save a deck for the first time, or "save as", I see no decks in the folder I select, even though I've selected the type (.mwDeck) all the files in the folder are. This makes it impossible to save over an existing deck file (I use changing version numbers when I revise my decks), and has become frustrating enough that I'm back to using vanilla MWS to build decks.

Fix, please.
