Mouse problem?

Gino,

Another user had a similar problem recently. The same suggestions might help you as well:

If you can use the mouse wheel to spin, but cannot use the middle mouse to spin, typically the culprit is the software used with the mouse. Logitech is the one that comes to mind most often (although the touchpads on Lenovo w540 laptops have a similar problem) have their software redefine the middle mouse to another action (Logitech likes to use the Windows Document Flip).

As Larry mentioned, the cause is typically a bad driver or an incompatible mouse. Also, double-check the mouse settings and verify that the wheel button is set to "Middle Click" instead of "Flip".

Let us know if any of these suggestions solve the problem.
