I just cut-and-pasted your second example into DrScheme 299.102, and it
printed the following to standard output, as expected:

((Stop at a B ABC 2) (('first (('A 'first 'right) ('B 'second 'right))) ('second (('A (Found a B)) ('B (Found a B))))))

So I'm not able to reproduce your problem.  Are you sure this is the
only difference between the two in the original code?

On a separate note, if this output is intended to be human-readable, you
may want to look at the pretty-printing library.  Search for pretty.ss
in the helpdesk.
