I'm in the same boat with my m65 rgb pro (see my thread). Corsair doesn't keep a downloadable library of older firmwares, what rationale is behind this is beyond me. If a fw update goes wrong, you're done. I had to buy a PS/2 mouse to regain control (notice that icue DOES NOT work with keyboard), and flash a very old fw which i had on my hd (can't even remember why or when i got it, but i've been lucky).

in my case the double click issue is related to the firmware (m65 rgb pro). with 3.05 it works correctly, 2.xx has the issue. 3.06 simply makes the mouse stop functioning (but it's another story). don't be surprised that other vendors hardware have similar quirks - most of the internal components all these brands use are the exactly same, and from the same factories.
