Windows 10 Word instability problem

[john92210]

I just loaded Windows 10 on my laptop. I have problems typing with Word 7. The curser jumps to different location in the document; sometimes the document zooms to a larger size, etc. I use a Logitech M 304 mouse and downloaded new software, but this did not solve the problem. Sometimes just touching a keyboard key makes the curser shift locations. I’ve also noticed, while working on the Desktop just touching the keyboard changes the icon sizes to “large”. Very annoying. I don’t know if it’s Word problem or a Windows 10 problem.

Weird.
Electrostatic discharge?
Has this happened before? What do you mean by Word 7?

But let's first check the mouse: could you test with a mouse with a cord, with your cordless mouse switched off.
What happens than?
