Hi, im from Malaysia,
i realize that once i start switching profiles. the wireless wont work that the middle scroll wheel and right click button will blink twice.
i also tested with the cable on. same. it wont work on other profile.
i also tried updating firmware which i believe i have the latest as it state that "Firmware is Last Version!"
Edit-also what i realize is i need the mouse to be close to the wireless dongle and press the pairing button to work.
