Hi - I bought a Saphira mouse yesterday, downloaded and installed the software (Firmware v1.0, Saphira Software v1.1) and tried to program macro keys. The software appears to accept alternate commands - it records macros and also shows single key substitute settings in the software - but the buttons never produce any behaviour other than the default. The two dedicated macro buttons on the side will ONLY do backward and forward (ie. in the webbrowser) and the L and R buttons always stay on L click and R click. I'm running WIndows 10 64 bit, and I;ve delted, uninstalled and reinstalled the software a couple of times. What now?
