Windows 10: Can't scroll when I press full-stop

Whenever I'm on Fandom, and I click fullstop randomly, I am unable to scroll down unless I refresh the page. Is there a way to stop this from happening? Is there a virus in the computer? I use chrome as my search engine but my device is Windows 11

Won;t stop scrolling

If you don't press down on the wheel and just roll the wheel forward or back it will scroll the page up or down. Pressing the wheel it will automatically scroll. You can adjust the behavior, how many lines it scrolls, of the Middle Wheel How To Fix Middle Mouse Button And Scroll Wheel Not Working

 

scrolling bad

New event. When placing cursor over a list or row of columns, even the volume bar scrolling is automatic and proceeds to one end of the series and stops. The scrolling also stops when I move the cursor away from the list but am unable to select anything in the list. Not all the possible lists are effected. Other sites have recommended mouse/kb fixes. Have tried all those but the phenomena persists. Have not had any known updates recently and don't have a restore point to try. Any other suggestions? W10Pro 1903

 

Won;t stop scrolling

Using win10 fully updated, pro on one computer, home on the other. Often, when I click on the vertical scroll bar, not at the ends, but in the middle, instead of scrolling one page, it just keeps scrolling, even though I used a very quick touch. It can go 10 pages before it stops. I thought it was the mouse so I changed mice, but it's the same, and it's the same on the other computer. ??? Using the common Dell mouse in all 3 cases.
