"The clean sheet of paper worked for me too! Thanks!

I hope it lasts! =)

Update

Alcohol and clean sheet turned out to be just temporary solutions. At least for my 3 years old Mighty Mouse.

I've tried this guide and i completely fixed the problem.

Totally recommend it!

Best of lucks!"

"I would like to add my answer as I don’t see it yet.

If you follow the link to the disassembly instructions or if you have taken the mouse apart already, you will see that there is a metal tab that is near each of the black magnets on the rollers . This is there to measure the resistance difference of the magnets so it knows that the roller is moving.

In my case, the tab was physically touching the ‘down’ roller. Well, if there is no gap, then the mouse cannot tell if that roller is moving.

TLDR: make sure the metal tabs next to the black wheels on the roller bars are not touching the black wheels. If they are, simply bend them back slightly."
