Not all of them, but on quite a few of my Xstore installs, when you are trying to move away from a page, even though you have saved the page and published it makes it appears like you haven’t made changes and the popup says
“Leave Site?
Changes that you made may not be saved.”
Even though everything is saved and all ok? i’ve noticed in on a number of Xstore installs
It’s been highlighted today, as the client mentioned the same, so I don’t believe it’s browser related, have you heard of this at all?
