Hi; For what it's worth, I managed to get Scigraph's demos to run under SBCL. There are still bugs (when you click on certain elements of the graphs, they keel over dead), but at least it is something. Please find attached a "cvs diff" listing. If this is not sufficient, of if the patches are not up to the usual McCLIM standards of excellence, please advise, and I will be more than happy to try and do better. Thanks for the software, -jm -- --- John Morrison --- john.nmi.morrison@gmail.com
