Left click doesn't work if I am holding Right Click. What can I do?

[Alex Noren]

Specifically I noticed this problem when I am trying to play shooter games like Borderlands or Call of Duty, etc. If i am aiming with right click and holding it, i cannot fire (activate left click). I have no idea what to do. Here is my mouse: Marvo G909+G1 Adjustable USB Ergonomic Wired Gaming Mouse
