Hey folks - I just moved into a home and wanted to be able to open the windows for ventilation while I paint some of the rooms, but the windows are stuck firmly. They've been painted shut, inside and outside, and even though I've freed all the parts I can reach inside, they won't budge - I need to scrape around the outside parts, too. All of the windows have storm windows covering the outside, though, and they're designed to be moved from the inside (which I can't get to!). With a great deal of effort, I was able to pop out the screen from one of them, but then there was still the glass storm window behind that, and I already felt I had come close enough to breaking the screen when I removed it. The storm windows are aluminum frame, over double-hung windows behind. Any advice on how to remove them so I can free my stuck windows?
