Hi Mike,

Sorry about the wait, I put the mail aside while CVS was down. I'm
CC'ing the mailing list now that it's back.

I've disabled the step command in the Elisp end. It doesn't seem to be
implemented by any backend, nor have an interface definition. (Anyone
know the history?)

This works for me. Can you post more details, e.g. a step by step
example?

The Swank frames aren't treated specially so possibly there is
something funky about the other frames your v'ing.

(As above.)

This feature isn't implemented in the ACL backend.

I don't have ACL installed to test this. Anyone?

The command isn't implemented in the CLISP backend.

These are as above.

The last ones sound nasty:

Anyone able to investigate?

I'm not wild about ACL's licensing mechanism and would prefer not to
install it on my computer.
