It happens when it's extra humid outside. It's in one room only.
Both the inside of the storm windows and the outside of the house
windows fog up. The windows have an air conditioning register below
them, which means the inside of the glass could be extra cold. I
would think the inside windows aren't sealed tightly, but one of them
doesn't open (i.e. it's a permanent picture window encased in wood).
The storm windows slide and their frames are not sealed against the
house. The permanent picture window storm window obviously doesn't
slide.
It's worse since we had the outside of the house painted, including
the window frames and glazing.
My great Googling skills fail to find a solution because it's a summer
problem and not a winter one.
What's up with this?
