i does not discover anything!, forget this paragraph, if i  use a 
options[i+1], i steel could not put a new object in the father's select, 
but the index grows in 2 units, so the first shows as a blank option. 
The second never shows because IE restriction(not allow option add from 
other window). So index are the same in IE and Mozilla.
