Nice try but no cigar. The AVTS 3.9.2 still has a problem with the opening page:
"This Ballot Station is Open" and "Accessing Ballot" and "Please insert voter card" only appear in English (twice), not English and Spanish.
I have rolled back to 3.8.1 for the Riverside demo.
p.s. There were 4 races which showed up with "Yes" candidates even in Spanish (Races: 130, 140, 150 and 160). This is a database creation oversight. The candidates were entered as "Yes" in both the default and Spanish language sets in GEMS and had nothing to do with AVTS 3.9.1 or 3.9.2.
