Windows 10: Cannot scroll down and folders are randomly selected

when I scroll down a page it suddenly scroll backs up and I cannot move the scroll bar down.If I press on the arrow keys it works again. On the home screen folders are randomly selected. Scroll down issue is also faced in Windows start button - top most option is always selected cannot change selection using touchpad.

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

 

No Scroll Printer Selection

Windows 10, Dell desktop PC. Sometimes when I select to print a document, the small, square print window that comes up has a single 'General' tab at the top. The selections are listed 3 per column. Out of that big long list, there are only 2 printers I
have used so far, Microsoft Print to PDF, and our Ricoh printer. As it happens, each is at opposite ends of that long list and it seems as if every time I wish to print, I need the printer that doesn't show. That requires me to scroll to the other printer.
Is it possible to edit/adjust the names of these printers so they appear next to each other and scrolling isn't required? All suggestions, ideas, comments any wish to offer will be greatly appreciated. Thanks, K.

 

Stop Scroll Returning to the Top of List

With Windows 10, inside a lot of applications, when scrolling down through a folder or search list, the screen will return to the top of the list. Try to scroll down again, and randomly it will return to the top of the list. You loose the section you are
scrolling through.

I need to get it to stop doing that,
