Sure, I can explain the process. To pick your lines for a starter, you typically look at the available options in the software or interface, choose the ones that best fit your needs, and then confirm your selection before starting. Let me know if you'd like more details!
Functions exclusively on a single line previously, but now fails when adjusting to lines above or below as with a mouse movement.
It's quite unusual. I came across this discussion some time ago. It might be useful for you.
It seems you're stuck without knowing further steps. Reinstalling Office and possibly Windows might help. Have you checked if Microsoft's support is available?
