Waste

I used to use Dupin Lite (which was quite satisfactory). I today bought Dupin lite 2. Upon launching (Yosemite 10.2), a menu bar appears, but no window of any kind. And there seems to be NO way of obtaining a window. The File menu instructs me to “get duplicates”, but HOW? I do expect applications to work before they are put on sale. Money back?
