The mouse works perfectle but when i tried to connect it via bluetooh it doesnt show up.  When i turn the switch to bluetooh it automaticlly does the thing, when you hold does 4 buttons. The status indicator blink twice and i didnt hold does buttons. I tried all 3 windows bluetooth things and nothing works. Normally my pc doesnt have bluetooh but i bougt a stick to upgrade it. Could that be the problem but i dont thing so because everrything else works beside the mouse.
