Just by pressing B?  I cannot reproduce this here.  Please tell how to
reproduce in "emacs -Q".  (Btw, byte-compile-file is not bound to b,
it is bound to B, upper-case, at least by default.)  What I see is
that after the compilation finishes, Dired moves to the line of the
.elc file just compiled, and the entry is refreshed.

How?

Tried that, still cannot reproduce.

Type "C-h l" and post everything that pops up in a buffer, I guess.
I'm really in the dark here.  You need to try to note what you were
doing that is somewhat special in those cases.
