...

I just tried the Apropos example on Allegro... whether started off in an emacs buffer or a console window or an IDE debug window. In each environment, whether just typed in or within a (mp:process-run-function ...) the listener is locked..

OK, so I tried with Corman Lisp 3.0 (using CREATE-THREAD) - no problems, no locking, like with LispWorks. Maybe someone on this list can try the same with ECL, so we've covered all Lisps on Windows with MP capabilities.

I tried the Apropos example under ELC and MP, it worked without any problem. Michael.
