Same here.
Mouse was working perfectly util about 4 days ago. Then it started not registering the left click. I sometimes would hear the clicking sound, but nothing would happen.
I have tried almost everything mentioned in the threads in this forum, but I'm not going to risk opening it up.
It's a shame because I love how the mouse feels, but this makes it borderline unusable. :[pouts:
Guess I'll contact my supplier and see if he can get in touch with Corsair about the issue.
