I have encountered this issue since I initially bought the mouse brand new (this is not a result of over-use wearing down parts). Whenever I bring the mouse back down to the pad with anything other than a feather touch, the middle click button activates on its own.
At first I could ignore the problem as I did not do much that would require me to move the mouse in such a way, but after recently starting to play more FPS games with a ping system bound to scroll-click, I have noticed myself pinging almost everything in sight due to it activating whenever I put my mouse back down after picking it up to re-center it.
I am running Synapse on default, I have not found any settings to be able to adjust the scroll-click sensitivity, I have updated the firmware to v1.2.0.0, I have fully uninstalled/re-installed the mouse drivers, and I even threw a holy-mary (that I knew had 0 chance of working) by following one thread’s comment that “turning off the LEDs fixed the issue”.
I could bypass the in-game issues by binding the ping to a different button on keyboard perhaps, however it would not fix the underlying issue, and the hair-trigger on the button is also a problem in other apps where scroll-click activates the auto-scroll feature, then suddenly I’m scrolling through the page faster than you can scroll through ‘terms & conditions’ to hit accept.
Please help, I am at my wit’s end and I need to know whether or not this is a fixable issue through some obscure setting / third-party app, or if I simply need to throw out this mouse and buy a new one.
