I also am experiencing something similar – the Book Page Turning Effect (in V. 1.18) is causing problem for my setting for Gateway-HTTP User. Not sure if this is a bug specific to v.1.18, because we were ok on this when we were using v.1.17. When turning off the Book Page effect then I am able to have this funtion work again. Any input? We really would like to keep using the Book Turning effect on our form(s) if is possible.
