Slime is a lot nicer than Ilisp, don't know why yet I like it much more, and the pace of developement is realy astonishing. Thank you. The bad things: (windows) Could not break ACL with C-c C-c or C-c C-b, nothing helped so the only way to exit an infinite loop is to restart ACL :( There is a bug in (defun user-init-file () "Return the name of the user init file or nil." (let ((home (user-homedir-pathname))) (and (probe-file home) (probe-file (format nil "~A/.swank.lisp" (namestring (truename home))))))) in windows if my home dir is "D:\home\qzma\" it tries to probe "D:\\home\\qzma\\/.swank.lisp" and of course fails miserably, yet i don't know how to fix it to fit both operating systems. (linux) comming as soon as I'll get home Ignas Mikalajunas
