I've procrastinated the final decision. I took the mouse apart and cleaned out all the fluff (well, it is 12 years old and been through hell with me). It's more or less ok now so I've got more time than I thought I had.

@Quenten This mouse is an ordinary mouse with a USB cable to the PC. I prefer them to wireless because they're greener.

I think the scroll wheel connections are worn out, which is why its sending ghost messages to the PC. I know its the mouse because it stops happening when I unplug it.

This is different and separate to the issue I had when the cursor wouldn't obey the mouse at all and became wildly erratic. That time I discovered I had left my pen lying on my tablet so the the two devices were competing for control of the cursor :P

No wonder it took him 50 years!

You're welcome, Calibre :)

Hmmm, let me see....

I think I have a free spot in the early part of 2022?

My dream house!

Hmph.

Nice map though :)

Or do it Remy's way :)
