FORMICA I love this app and have used it for over a year. But it just takes too darn long to open after I've double-clicked on an archived file. Unfortunately, it's a long enough delay to cost it one star in what otherwise would be a 5-star review. Also, it still occasionally has the problem that the previous version had: it runs into some problem while unarchiving, so it makes that failure sound and gives an error message, but upon further inspection, they actually unarchived fine and are problem free.
