Escape button macro

Hey guys, quick question, I have a Razer Nostromo (yes a little outdated) but it works great. I am using it for autocad drawing and all the macros that i have set work great except for the escape button. When i set a button to match the "escape" button, it screws up my main keyboard and nothing works and i can't even type anything. So I tried creating a macro for the key up/down escape button and assigning that to the nostromo, and the same thing happens. Any thoughts?
