That's a known bug when you translate and compile with Borland (or Lcc).

 From my old rough notes (which I should really add to SourceForge):

  "Things compiled by Borland (or Lcc):
   get_key() requires an extra keypress (even Shift key is enough)
   before it responds to the first keystroke.
   gets(0) and getc(0) seem ok."

I don't know how to fix it. 
Maybe someone can read the Euphoria source and figure this out.
