Can you provide a recipe, as in: what file or URL to visit and/or what text to insert before starting the zoom commands? Also, do you zoom in and out repeatedly, or just zoom in that many time? And if it just takes a small number of zoom commands, why do you say it takes half an hour? what else needs to happen during that time to see the problematic display? Thanks.
