if i hit return after entering the password for an archive (instead of clicking ok) the whole program seems to freeze up. if i open another archive it will show up in the window but i can't do anything with it. if i double click the icon i get no preferences. a blank unarchiver window will just stay in the background and can't be force quit (or regular quit). it happens every time. this is a TERRIBLE bug and if it's been reported i apologize, for i don't have time to read through this thread, but it keeps me from using unarchiver as hitting return after typing is something ingrained in my mind.
