I bought a Razer Orochi mouse recently, hoping it would improve my workflow with CAD and 3D modelling programs. After realising that the software it comes with (synapse 2.0) is total garbage, I resorted to using BetterTouchTool, and I have successfully mapped all the extra buttons, and everything is jolly and works great in autocad, photoshop, rhino etc. 
however!!! the mouse works great with every program i use, except Blender, where the middle click does not work. this bugs me a lot. it works great when i quit BTT, but than i lose the functionality in the additional 4 buttons on the mouse (which i use to navigate between spaces and stuff...)
