[slime-devel] incompatible protocol?

Hi -- I am getting weird results with my remote slime connection.

I am running and SBCL 0.9.16 and swank from SLIME 2.0 on a remote linux box, and connecting with SLIME 2.0 on

GNU Emacs 22.0.91.3 from 2006-12-16.

When I `slime-connect' I get this prompt:

Protocol version mismatch. Continue anyway? (yes or no)

If I type yes, then I can do things:

CL-USER> (asdf:operate 'asdf:load-op :elephant) ; loading system definition from ; /usr/local/lib/sbcl/site-systems/elephant.asd into #<PACKAGE "ASDF0"> [...]

But I can't seem to get values back! --

CL-USER> (+ 1 1) CL-USER>

On the other hand, I can print:

CL-USER> (format t "~a" (+ 1 1)) 2

Is there a way to get the normal expected behavior back?
