I'm less experienced in terms of website building, but I have had this issue and below might be of help. If not, maybe someone with more experience can help?
I always found this issue a bit of a hindrance, and, afaik you cannot go back within scenes. The user will need to activate the previous page, by working within the page space. A back button within the scene.
I ended up creating my hype websites using a separate folder paths with index.html files to get the new page to load. This way, when someone uses the browsers back button, it does what it does in the way we are used to.
2) www.mywebsite.com/about (index.html file in this folder)
It's an instinct web surfers have and it would be great to have the browsers back button functionality working within scenes - but that might cause more problems, and I don't think that's a priority when the above works fine?
