A question

Despite admonitions from people at Symbolics, I still like (sometimes) to
debug my program by stepping through it. Previously in Release 6 (or 5), 
I was able to step through functions and the stepper would only display 
the current lisp form that I am looking at. However, the stepper facility
in the trace function has been modified in Genera 7 so that it prints out
all lisp forms which are at same or below the current evaluation level.
This is VERY slow and makes stepper almost useless except for small functions.
Symbolics software support suggests that I use 'break' command, but that
means I must know where the problems is and there is no way to evaluate
lisp forms at a level below the breakpoint. Furthermore, putting and
removing breakpoints is time consuming. It is tantamount to putting print
statements in Fortran (well, a little better). Most of debuggers (of other
languages) have the stepper facility much like the one available in Release 6.
My question is: is there an option that you can set to change the stepper
to a less verbose mode (more precisely, to the pre-Genera look).
Thanks for your help.
