Hello Chapel, I think I know what is wrong.

("3.3.1" "2.0.4" "2020-04-27" #P"/Users/oscarchappel/common-lisp/mcclim-0.9.6/“)

The last item indicates that you have a locally cloned (and possibly old) version of McCLIM which is loaded by ASDF. Try deleting the directory #P"/Users/oscarchappel/common-lisp/mcclim-0.9.6/“. Then try quickloading McCLIM again (Quicklisp will automatically download the latest version). Good luck, Nisar On 31/05/20 9:08 pm, Oscar Chappel wrote:
