    Could you possibly have additional elements using the same ID name on the DOM at the time?
    Don't think so. Think it's all solved now as I said. Initially I used a single box to show tips and details for pins/tracks. Then modified the box to include images relating to pins forgetting I'd used it for the tips.

    Names can be a problem. Once lazily used names x and y for position in some interactive games, only for them to stop working in Chrome when Google added undocumented properties x and y.

    I've had this a few times recently on one of my Amazon bots (everything is there when you look at the html but it doesn't exist).



    To fix it I've taken to using document.getElementsByClassName("info")[0].innerHTML=""; to fix it with and using the classNames of the element which means your div will need to be

    <div id="info" class="info"></div>

    equally though a better approach would be

    var info=document.getElementById("info");
    if (info===null){
    info=
    document.getElementsByClassName("info")[0];
    }
    if (info!==null){
    info.innerHTML="";
    }

    An alert at top of script shows correct innerHTML content every time I refresh the page. Then the property is null when I try and use it in mouseover.

    Ah! Nostrils! Neither defer nor moving the script to bottom of page has worked. Must be some odd fault somewhere. Thanks anyway.

    Yep, put script at the bottom of the page so the html will be loaded first, or use 'defer' for external scripts being linked to:

    This is your answer.
