Huh?  The next reflex after the "Next Reflex" fails is to read the
question and deal with the selection.  Like these eula's that force
you to check the "I've read this text" box before you can go on.

  Idioms
  apart from
    Also, aside from. Besides, except for.

so yes, I meant "apart from", so I wrote "except for".)

It's not *them* that I'm talking about, it's they're students who will
trip even more.

But you ignored the maintenance problem -- will you do it?  Will you
come up with a different name for each version of your book if it uses
a different language?
