So, has the scroll button in your mouse suddenly stopped working and that too only with Google Chrome? If yes, read on.
If you’ve got the ‘Smooth Scroll’ Extension installed it is the culprit. My Chrome was working perfectly until I started the computer tonight. Apparently, this extension got updated today and stopped working properly.
Disable the update for a while and see if the publisher realizes that the update has broken the extension. Even better, uninstall the extension if you can live without it. If you are looking for an alternative instead try Smooth Scroll up and down.
UPDATE: The Publisher has now updated this extension. Restart Chrome and check if Scrolling works. If it still doesn’t, re-install the extension from here.
