      currentOpp.StageName = 'Closed Won';
      currentOpp.CloseDate = System.now().date();      
      Database.update(currentOpp);

We have the Closed Won stage set at 100% Probability. If we manually move the Oppty to Closed Won and save, the Probability updates to 100% jsut fine. But when using the code below, it updates the stage correctly but the Probability remains where it was. We have this working in our Prod instance, but we're attempting some stage renames (probabilities staying the same - and not changing Closed Won), but it's not updating the Probability field.
