Real Problem - Probably with Win 10 Settings

If got an exasperating problem.

First I thought it was my LibreOffice. Open a spreadsheet and it opens it at cell AMJ3293 (or whatever the bottom far right number is).Scroll to the far left and I can see my spreadsheet, but it won't stay there. It wants to keep going back to column AMJ and bottom right number. This all started after I tried to do a sort about 4 times because I kept getting the parameters wrong in LibreCalc. And I cannot get it to stop. So I cannot do ANY LibreCalc work. I think that was the original cause. Or at least when I noticed this starting. I actually do not think the problem is with LibreOffice because I have related problems with my browsers and also File Explorer.

Then I thought it was my browser. Brave, Chrome, Edge won't scroll the scroll bar on the right. Only the Up/Down arrows work. Only FireFox works correctly.

File Explorer is also a problem. Move the cursor to the left side and the left scrolls all by itself, even if I want it to be stationery. It won't stop scrolling until I move the cursor out of the left directory frame.

Has anyone got any ideas what is, or might be causing this strange behavior? It's nigh on impossible to get any work done.

Hi idgat

Changing the wireless mouse seemed to work. Thank you very much indeed :)
