when making large screens i.e. 20x30 once scrolled the rulers become jumbled and do not show measurements properly. turn off and back on, ok again until scrolled
well it really doesnt have to be a large screen, if you zoom enough to where your screnn does not fit on the page and then scrool, that's when it happens. I initially said large screen because I was building a 20x30 and when zoomed in to move around the screen the rulers would get bugg. The numbers will become un useable. If you turn rulers off and back on they shoe correctly untill you attempt to scroll. Hopefully explains ok
