my daughters was on the computer this morning, I don't know what she did but now my mouse wont scroll down a page. When you move the wheel, nothing happens.
Does anyone know what she might of 'clicked' and how I can get it back?
If it was a ball mouse it may just need cleaning.
Give the underside plate a half turn and let the ball drop out.
Use a cotton bud or cocktail stick to remove the general trash that will have built up.
If it is a corded optical mouse gently wipe the underside face plate with a damp cloth, NEVER use nail polish remover or similar substance.
If it is a wireless optical mouse check the batteries as they may be on the way out.
