I have a new Scimitar (Delivered Friday) using it with a K65 and it is barely usable even as a standard mouse for desktop activities, click's not actioned and random hesitation and lock up's moving cursor around the workspace. I have attempted to set lighting functions but find that is loses settings after a few minutes of use. I'm not using any third party software or have anything mapped to the buttons. Are people RMA'ing their mice or is it thought to be a firmware problem? Windows 10 - Asus ROG VII Hero - Nvidia GTX980 Ti Graphics Card -
