When holding the left or right mouse button on my Razer DeathAdder, it intermittently stops to register the hold. For example, when I move a Windows window, it only moves a bit and then drops. I have been using the mouse without this problem for over a year and it recently occurred without me changing neither software settings nor installing new hardware.
I use a Razer DeathAdder left hand mouse with "3500DPI Razer Precision 3,5G infrared sensor", Model number RZ01-00151700-W1M1 on Windows 10 with the legacy driver. I don't use the Synapse driver though it regularily asks me to install it which I always decline, I hope it doesn't install something without my permission.
Is this a software problem or a hardware problem and how can I get my mouse button hold to work reliably again?
