All of a sudden, when I try scrolling through a web page, for every click of the mouse-wheel, it moves up or down a whole page, not smooth scrolling.

Yesterday it was still scrolling smoothly. What could have caused this and what can I do about it?

EPILOGUE: The problem disappeared somewhere after playing with scroll wheel settings, but they were already correct. I think this behaviour was perhaps just Chrome being wobbly.

    It’s an option in your mouse settings. Go to control panel. – Appleoddity Oct 31 '17 at 4:31
  • @Appleoddity Yes, it's a setting "Multiple Lines at a time", vs it could be "One screen at a time. It has always been on the former, and still I get this. And only in Chrome. – ProfK Oct 31 '17 at 4:55
  • Ouch. I stopped all Chrome processes, restarted and it's still the same. – ProfK Oct 31 '17 at 5:01
  • I had similar problems. Each browser now responded to wheel movement radically differently. There was also a significant response time delay such that the wheel had turned quite a bit before any scrolling had even started. Even adjusting the Additional Mouse options did not resolve the problem. Things were not sorted out until I set System Property Advanced Performance Visual settings to manual and checked every box and then clicked on Apply. Even then it required a computer reboot. – Sean Dec 23 '17 at 4:43

Check your mouse wheel settings to make sure switch the number of scroll lines to the default 3 lines as below:

Go to Control Panel, open devices and printers, click mouse, go to scroll, change the number of lines being scrolled. Mine was to 100 lines, I changed it to 1.
