There is now a photo of the tool my wife now uses to get at our screen in my links below. Basically, she is 5'6" and the screen is high up. It's simply a broom handle cut in half, varnished with a boat hook screwed onto the end. Total cost £5. She can now do it all including pushing the screen home. Now, how do I get her to have tea ready when I get home without violent encounters?
