[Click] click-align gives incorrect output

[Eddie Kohler]

Hi Tom,

I think you might be confused.  In "fromhost_cl[0]" it is allowed to omit the 
"[0]", so your "fromhost_cl[0] -> ARPResponder at 3" connection is still there, 
fourth line from the bottom.  The configuration looks totally valid to me. 
Note that in your input config fromhost_cl[0] -> ... -> tap0 -> fromhost_cl.
