I'm sure this is the wrong place but I use Windows 10 and the Edge browser normally.
Larian.com/forums does not accept my login when I use Edge (it goes into a loop of accepting my password but saying log-in again) so I have to use IE11 for this site.
It could be Edge browser is rubbish or perhaps your forum software doesn't like it.
In any case I thought it was worth mentioning.
