The only solution is to decrease the amount of moisture in the air, or increase the temperature of the air-surface interface (anywhere where the air touches any surface). Air flow across the surfaces often eliminates or ameliorates the condensation problem.
"Condensation occurs when moist air comes into contact with cool surfaces, such as glass/metal. This type of condensation appears when the dew point in the air is higher than the temperature of the glass."
"Whenever there is excess humidity, it manifests itself in the form of condensation on the coldest area/surface, which is normally the windows or the walls. The warmer the air, the more moisture it will retain, so when air in your home/cab comes in contact with the colder glass/wall/roof surface, it is subsequently cooled and moisture is released in the form of condensation on the glass."
jointsmith posted the truth. Folks in high humidity environments have few options (unless you can raise the heat of the surface, as Denny suggested earlier), or unless you can use a humidifier.
I remember visiting Williamsburg, VA many years ago. The old buildings had single-pane windows and big pools of water outside every building: high-humidity outside air, air-conditioned old buildings with cold single-paned glass. When we got to our cars, and turned on the air-conditioning, we also had to turn on the windshield wipers (condensation forming on the outside of the windshield), The car's air-conditioning system evaporator take a workout.
