CLisp for dummies



Hi,
I'm used to working with GCL but in some of my students systems xmaxima
runs with CLisp and I've failed to help them with this very trivial
issue:

 The following restarts are available:
 R1 = Macsyma top-level
 
 1. Break [1]> 

How does one go back to Maxima? I've tried R1, :q, :R1, (R1), (run)
and some other things, without any success (the students usually kill
xmaxima and start a new one).

Cheers,
Jaime
