Unable to scroll a long message in WhatsApp while typing

Ok, I just updated whatsapp but it's still the same, unable to scroll the message.
I'm not sure how to "clear the cache", I don't think it would help either.
My mom has never been able to scroll in a long message that she's typing.
It's just that you CAN scroll a message on android and it just does not work on a windows phone somehow.

 

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

 

Repairing Windows XP can Break Windows Update

Microsoft/Windows Update Program Manager Nate Clinton has revealed that repairing a Windows XP installation using the Windows XP CD can potentially lead to users being unable to install updates when using the latest version of Windows Update. The problem, which does not appear to be widespread, occurs because the Windows XP CD replaces all system files, including those of Windows Update. Because the latest version of Windows Update uses a file which is not present on the Windows XP CD this causes a registry mismatch which can result in Windows Updates failing. So if you have recently run a repair install on Windows XP it is recommended that you either take a look at KB article 943144, check here for a workaround or contact Microsoft.
