Your condensation is caused by the warm, moisture laden air moving toward the cooler window or door wall, "it becomes cooler and cannot hold the moisture it held when it was warm. The moisture is then dropped and appears as water on the glass and frames of windows and doors" . Of course this happens more in in the winter months because of the difference between the indoor and outdoor temperatures. The tighter your home, and the better the insulation, the greater the amount of condensation. I think your new windows may be contributing to that as well :-) The only thing, besides a dehumidifier of course, would be to increase ventilation way to remove excessive moisture from the air. Here is a list of a few things you can try
" Install storm windows or replacement windows with double or triple glazing.
Shut off furnace humidifier and any other humidifying devices in your home.
Be sure that louvers in attic or basement crawl spaces are open and that they are large enough.
Run kitchen or other ventilating fans longer and more often than has been your custom.
Open fireplace damper to allow easier escape for moisture.
Air out your house a few minutes each day. Air out kitchen, laundry and bathrooms during use or just following use.
If troublesome condensation persists see your heating contractor about an outside air intake for your furnace; about venting of gas-burning heaters and appliances; or about installation of ventilating fans." from this site. Hope this will help out.
