changing polling does nothing and yes i also have a toggle with K57 rgb wirless keyboard. its not a problem of wirless - i ve the same issues if both devices are connected with usb and toggles unplugged.
like all others said - all worked fine before the update - my devices are 4 months old - not the quality i expected from corsair..
i was not able to install the old software version - can you please provide a soltuion as its clearly not a user fault?
like i said blowing air between the buttons helped a little bit - dont want to go to my local dealer and start a discussion if the mouse is working or not...
