LispWorks is still a commercial CL :-)

For now, I've defined a class with an interface very similar to the
existing list-box%, and implemented it, crudely, using horizontal
panels and text fields.  Should be fine for my immediate application
prototyping purposes.  In a month or two, after I've had some time
to look more closely at mred and mred extensions (maybe mrdesigner
as an example), I'll take a stab at implementing something better.

Thanks,

Mike
