Any updates for the official fix? None of the above have fixed my side buttons not working even after them seem to map correctly in cue. Can not even map a simple back button to the mouse.
I got the mouse in Oct 2015 and it worked perfectly for the first few months, only recently has the side buttons and all mapping (even making the dpi button a back button) no longer works.
Tried restarting, un-installing cue, different firmwares for the mouse, different versions of cue.
