slime setup on Win10

xI'm a retired "old guy", and a hobbyist code monkey. :) I've decided to revisit Clisp/emacs/slime/quicklisp for something to do. Got most everything working on my Win10 laptop, except that when I do a M-x slime in emacs, slime chokes at the very end on a bloody windoze short directory name to a TEMP file. This warning occurs while running the swank.fasl file. Any way to edit that sucker so that I can give it a "full" filename? Thanks! -- Duke
