Hi all. I have a handle on a UPVC window that's refusing to budge. It was working fine until recently - we open it once or twice every day - then suddenly refused to move. I can depress the button, but no matter how hard I try, I cannot force the handle to turn. There is half a key stuck in the lock, but that's been there for years.
Any ideas or advice would be gratefully received.
