Kani,
Perhaps there is more than 1 problem; improper sealing and condensation. If the moisture is showing up when the windows are shut and there is no rain, then that points to condensation, especially with aluminum windows. Aluminum windows transfer heat (or cold). If the house is warm and humid when the windows are closed in the evening, then the windows are cooled by the nightime outside temperatures, the interior moisture will condense on the aluminum frames and drip down. What elevation are you?
