Since I bought the mouse, the scroll wheel frequently stops working. Until last week, unplugging the USB and then plugging back in would fix it. However this last week, I now have to unplug and replug several times before I can use the scroll again.
No. the macros I set up involved the side buttons and not the scroll wheel. They seem to be inconnected to this problem.
It seems this is just a fault with these mice which Corsair are very slow to recognise and fix.
I did just click on the support button, but it seems that their support is down for maintenance. Maybe they use these mice too!
I have just discovered that, like the person who posted above, if I press down on the scroll wheel I can scroll by dragging the mouse, but that is less useful than scrolling by rotating the wheel.
