Hi all, So I've owned this Razer Mamba Tournament Edition (Model No. RZ01-0137) for about 6 months now. Literally yesterday the up down scroll completely stopped working, while side to side scrolling did continue to work. Scrolling with other mice work but this does not. I did not have Razer Synapse installed. I then installed Razer Synapse (version 1.82.35) from the Razer website to try to remap the keys, however upon remapping the Scroll Up and Scroll Down commands to other keys that did not work either. I'm currently running Mac OSX 10.10.3 Yosemite on a early 2015 Macbook Pro retina. The mouse has been sitting on my desk since I owned it so it has never been crushed, dropped or anything like that. I would appreciate any sort of input and help. Thank you!
