I have a razer naga 2014 and run windows 8.1 and the latest version of TS3. I have updated all drivers for the mouse and windows.

The issue I have is when I am not using Ts3 I can use the side buttons on my mouse fine. As sson as I connect to a server within Ts3 the buttons disable for some reason. My PTT button is currently on the side buttons too.

I have also tried switching from the 64 bit version to the 32 but no luck.
