I've browsed the help forums here for the past couple days and have found no solutions that have worked. I have a USB Wheel Mouse Optical plugged in to a laptop with the most current Synaptics touchpad drivers installed. I also have the most current Intellipoint drivers installed. Left, right, and middle click buttons work, however the wheel scroll will not work. I have tried most everything I could search for including uninstalling/reinstalling drivers, ensuring registry value for wheel scroll is set to >0, and installing a different mouse driver, but wheel scroll still will not work. My Microsoft USB Wheel Mouse Optical device in the device manager has no "advanced settings" tab where I can force it to assume a wheel, however the Synaptics PS/2 Port Pointing Device touchpad has an advanced setting that is already set to assume a wheel mouse. I have also tried disabling the touchpad in the Bios, but has not affected the wheelmouse scroll. It's painful not being able to use a wheel scroll. Please help!

Maybe it's busted. Does the scroll function work when you use the mouse on another computer? Help me Jebus!

I feel embarrassed saying this but I was so sure that the mouse was new that I didn't bother checking a different mouse. It was the mouse, not the computer.

We all sometimes overlook an obvious possibility. I'm glad you got it figured out. Help me Jebus!
