Thank you Carl. I actually move this conversation to the Q&A as per your advice and got some feedback. I’m trying to resolve some issues between our server and Lectora and as soon as those are sorted out, I’ll put a blank title with the navigation keys that are malfunctioning with Chrome. And yes, I can see the keys in the Preview mode and when published through other browsers. I’ll try your suggestion to change the image’s format and test it.
