Thanks for the reply! I'm happy you're looking into it. It's actually not an IE-based browser, it's a brand-new rendering engine. Edge is MS' attempt to break with the cruft and "support the modern web." Their words. I am thinking the fault is with Edge. I was just wondering whether there's a line from you to MS, to talk to the Edge devs. I'd think it's MS that needs to fix Edge, not you who needs to change roll20. Though if you can work around it easily, who am I to say no to that :). I know that roll20 works great on Firefox and Chrome. However that's an extra hurdle for users who want to try you out, to have to install those browsers. I like "as few barriers between potential users and the service as possible" as a general guideline. I fully get that IE is just a no-go zone. But Edge, since MS wants that to go toe-to-toe with Chrome, that's a different story. They're close. They didn't quite get there in time for Win10 release.
