This problem was introduced by ZS in March 2023 with these commits: https://bitbucket.org/tmidas/midas/commits/25b13f875ff1f7e2f4e987273c81d6356dd2ff53 https://bitbucket.org/tmidas/midas/commits/2a9e902e07156e12edecb5c2257e4dbd944f8377 by setting d.style.position = "fixed"; which prevents the scrolling. I have no idea why this change was made, so it should be fixed by the original author. Stefan
