When I have opened threads over the last couple days, 1 in 3 lock up and I can't scroll. I have to refresh the page and it is corrected. Not a biggy, but maybe an issue needing attention.
Most likely a problem on your end. Have you tried turning your device off and on again? What device, browser and OS are you using? Have you installed or updated any plugins lately? Try disabling your plugins and see if the problem goes away. Try another browser and see if the problem still occurs there.
I guess edge is just windows 10 for now. Try disabling all your addons and plugins and see if that helps. If it does, then them back on one at a time to see if you can figure out which one is causing problems.
Not yet, only Beta type out there. August is the release month, no known date yet. Many new features and some old ones that scared people off from 8.1 Windows 10 and Edge will be released together. Viewable on Pc and Android. I'm betting Chrome will snap to and try to outdistance from Edge once the features are fully known.
