I have a double entry Schengen Visa. I have already used one entry into Spain, and will be using my second entry in a few days (from Africa to Spain). Once back in Spain, I would like to travel to France for a few days. Since both entries will be used at this point, will a roundtrip ticket from Spain to France to Spain be considered an entry? If so, what can I do? If no, does this mean that I can travel freely within the Schengen countries from Spain, even though my double entries have run-out?
