We introduced a couple of bugs in the initial Jaikoz 9.3.0 release that have since been fixed. so if you have downloaded Jaikoz 9.3.0 before October 19th please download it again to resolve these issues. You can check you have the correct version of Jaikoz 9.3.0 by checking the About window, the build date should say 19 October 2017. If its earlier than that you need to re-download from http://www.jthink.net/jaikoz/jsp/download/start.jsp
Sorry for the inconvenience.
