Why would my window close itself?
It's about 11 degrees Fahrenheit outside and probably around 65 inside. I opened my window because my room was really stuffy and it had been frozen shut. When I got the window open it felt like the bottom of it was heavier than usual and it basically fell back into place, slamming shut. But when I tried to open it again it stayed open and worked like it usually does. I was wondering if there was a reason it would do this, maybe something to do with the pressure of the room or something? My door was either shut or open just a crack, but it definitely wasn't open more than an inch, if that helps at all. Thanks :)
