@carl, yes browser and OS should define locale, but you should be able to change that dynamically.
@darrel. I tried changing parts of Trivantis mediaelements.js When publishing a message occurs ‘you are overwriting a build in Trivantis script’ ok, thats fine. I want that..but it doesnot do it. The original file stays there and not my changed one. In Lectora Online that is. I do know older versions of Lectora desktop did replace files.
Im gonna see and try to get your code working in a webwindow Darrel 👌😁
