Page keeps asking to save

Thanks David! So strange. If I use Safari, I don't get the issue. If I use Chrome, even in incognito, I get the issue. Any idea what it could be?

Well just to be safe i tested on FF and Chrome and Safari - all worked ok.
Which means the issue is local ( or my Mac just doesn't care :) )

Cookies, Caches, LocalStorage in Chrome can get a bit overloaded. Sometimes, sounds silly, i have had to shut down my machine and restart it to get Chrome to empty its memory.... might be worth trying
