This is due to bad ventilation. All upvc windows are fitted with espag locks with 2 locking positions, try putting the opener on the first catch to allow ventilation. Also an option to overcome this is to install face mounted trickle vents onto all frames and this will give constant ventilation and stop mould from occurring.
