Thanks for the info. I just had a quick look at Clozure CL - as you say, the main Gui library is for apple. The other gui library is labelled 'under development' but also 'last modified: 6 years ago' :( I wonder whether the (I'm told) good commercial lisp offerings have hampered lisp adoption, in that people who use lisp a lot, pay for commercial offerings, leaving the free stuff less used and maintained? Then newcomers, who don't want to pay to do hobby projects in a new language, are discouraged by the less maintained free stuff.
