Actually, that will make the issue worse. Warmer air holds more moisture than cooler air, and when the warm air meets a cold surface (like a window), water can condense and settle onto it.
A dehumidifier placed in the room should stop window condensation.
Also, they sell products called window film kits that would help.
IT is from the change in air temp from the inside to out, and the only way I know of it to get better windows.
Sorry I did not even think of that, Texas don't get that cold, also a fireplace may do it.
Well you can also keep you home the same temp as outside, I would not recommend it.
if it is in your car you can crack your windows open just a little bit.
