Very nice app :)
As a Lisp beginner and coming from eclipse I tried a handful of "IDE"-Solutions on windows. But either they are to low-end or they showed some other glitches like not "correctly"-communicating with the REPL. Eventually I found LispCabinet. And in my opinion it is the easiest to use, out-of-the-box, Emacs and Slime based, working Lisp programming-"environment" on windows (for me Win7 w/o any trouble). I've never used Emacs before and I strongly advise every new user to consult a entry text on emacs. The online documentation also contains a wealth on information.
