Indeed, it didn't notice the latest KB firmware update. FINALLY this long awaited fix for the terrible keyboard dropouts was released, making this keyboard actually usable ! There's also a touchpad driver too, which finally gives access to multi-fingers gestures etc... I actually had to run the FW update twice as the first time it messed up with the touchpad driver, but running it once again fixed it. The update process itself seems to update both KB firmware and the touchpad firmware, and after that you need to install the ELAN touchpad drivers.
