Ross Tell her that the last issue of Fine Home Building has an article which metions a company that can make storm windows for any window - even thoses that are out of square. Can't find my issue at the moment, it was a short one page article about a restoration suppliers convention - has a photo of reproduction carpets, near the front of the magazine. Hope this helps - if I find the article I'll send you a better reference and the company's name - should say when I find it as I am hoping they also make screen door - if ever there was a door that is not square it's my front door :) (200 year old log cabin, leans a bit to the west).
