Every time I play a game or even do a puzzle using Google Chrome, the piece I click always "sticks" to my crusor (mouse) and won't come off. Even if I'm not clicking, the piece still follows my crusor around even if I click elsewhere.

HELP!

Have you tried using a different browser?

There are known issues with Chrome extensions ...

Also, have you tried clearing the browser cache …
