I feel like most people wouldn't have too many issues with the Logitech Gaming Software or compatibility. Still, if you ask for a refund you should probably get one.
FWIW, I'm rocking the g13 keypad, the g910 orion spark, and the g700s mouse in addition to some logi speakers and webcam - no compatibility issues here, all working like a charm.
Maybe the solution is for Logitech to refresh the g13? I'd bite.[/quotemsg]
from what I understand, there was a refresh of the G13 a long time ago. One that supports a firmware flash, and one that doesn't. Mine doesn't support new firmware.
The issue with mine is really odd. Everything will work fine for so many keystrokes, and then it will stick on the last one - so, if you're walking forward, or strafing, all of a sudden, you're stuck walking forward, or strafing. Only happens in game, and when you close the game, it's back to normal. This happens on more than one computer, on more than one game, but only when I'm using the headphones. If I'm just using the G13 and G602 there's no problems.
