I am receiving consistently a Javascript error in the use of image maps with links as an automatic popup to a topic (html file). The error states "An error has occurred in the script on this page. Error: 'BSSCPopup' is undefined. Code: 0 What can I do?

My image maps linked to a html topic work if I use "Display in frame".  They do not work any longer in RoboHelp 2015 (updated with ALL patches) when I use "Display in auto-sizing popup" or "Display in custom-sized popup" where JavaScript is used. Any ideas? Must I have JavaScript installed to work as the scripting language in RH2015?  My IT Team says I never had it before, only JAVA.
