I just bought the Poseidon z RGB (with brown keys), out of the box it came with a couple of issues:
1. The '[' char is randomly appearing whenever I type, and if I click the '[' key, it just keeps on printing on the screen (without being physically pressed).
2. None of the fn combinations work at all.
I downloaded the latest software, and updated the firmware successfully to version 51 (btw, it keeps on saying 'you don't have the latest fw version, the latest version is 51 and your version is 51'- which is also kinda silly).
Is there anything I can/should do before I return the keyboard?
