This is a weird problem that i encountered with my beat-up "HP Pavilion Gaming Laptop 15-cx0xxx". With no apparent reason my scroll wheel activates the shift key and it's getting real annoying. If I go one notch up or down with the scroll wheel it presses down the shift button and then if I go another notch up or down it deactivates it. I don't know a better way to express what is going on. Restarting the computer didn't work, but i have yet to test it with another mouse. I'll still have to see what the steelseries engine has to say about my mouse, but a very strange problem overall and i haven't seen anyone make a post about this kind of an issue anywhere either. I'll update this thread if I can fix it in some way
