Thanks for all your tests.  But the info you give above shows that
we're not talking about the same thing, unfortunately.  I'm using the
Professional Edition of LWW and I have a custom-built console image
that I invoke directly by just setting the `inferior-lisp-program'
variable in my .emacs file.  If I start an "external" instance of a
CAPI-enabled LispWorks and connect to it using `slime-connect' like
you do I don't have FLI/CAPI problems and I never had them.

Hm, I wonder why you experienced hangs up until last week.

Thanks anyway,
Edi.
