In solidWorks 2013, if the scroll button is pressed, it is possible to rotate the part. But this function no longer works on my machine. I tested with another mouse but it doesn't change anything. Is there a checkmark to select to enable this feature ? (I can't find anything). The problem may be with the drivers
In summary, it can be the drivers, you can update them and see if it works, it may be a problem with the config window that has jumped, to see in the control panel! Or your broken button?
Tutorial based on SW09, but the operation remains the same regardless of the later versions, just the graphics change.
If you already have a backup (sldreg file), reload it. If you don't have one, save a colleague's settings (the position where the mouse works properly).
If it doesn't solve the problem, it can't be a bad thing. This approach solves other problems!
