Back to it's maker to ask what's up. Most likely a driver from them issue.
When I play Fortnite i want to build quick. I noticed that my gaming mouse "Star Raider
CND-SGM1" doesn't recognize when I FIRST hold my left click and than I clicki on "back key" on the side of my mouse. All other combinations of clicking and holding works... I uploded a picture of what keys I mean here: https://imgur.com/a/jBmpfJL
I tried to test my mouse here https://unixpapa.com/js/testmouse.html, but this specific combination also doesn't work.
I know what is keyboard ghosting. But I guess that mouses have same problem???
My question is... if your gaming mouses have the same problem and how do I know which mouse has this problem and which doesn't... How to fix this?
Thank you for your answer.
