Jerry has a new laptop with Windows 10 and his mouse doesn't work. He tried it with a different computer and it works. Leo says the problem with wireless mice is that they fail without notice. The dongle may be the culprit, but it may also be the batteries. Since it works fine with another computer, that tends to point to a driver or the specialized software that came with the mouse. Jerry should just reinstall the software. He can also try a different USB port. One of his ports may be broken. That's why Leo prefers the good old-fashioned wired mouse. It's reliable.
