I've embedded a Greenfoot Scenario in a own website. Unfortunately my game does not react after a second start. Mouse input does not work. I have to clear the cache first, but then sometimes it does not always work. Could it be because I test my website with localhost. Or is there a kind of refresh for <iframe>? I just realized that I have to refresh the site in Firefox, Edge and also in IE.????? Does this have to do with <iframe>?
