I just got my x20 and its a good mouse with one major deal breaker. My biggest issue is that you can't unlock the scroll wheel. I thought I had a work around with the right and left scroll wheel click. I tried to reassign the key from scroll left and right to scroll up and down. It works to scroll except that even if I hold the button down it only does 2 scrolls until I release and press the button again. It doesn't make sense to make those buttons not repeat if held down. With all the scrolling I do this is a deal breaker for me if I have to either manually keep scrolling the wheel or pushing the wheel left or right to scroll. Is it possible to get this changed in the software.

So I tried to assign the scroll left to up and the scroll right to down and now it seems there is a bug. If I hit the up button it works then when I hit the down button its like the button is stuck until I turn the mouse off, if I start with down then up it continues scrolling up forever until turn the mouse off. It seems whichever I do second it just sticks forever. I sat for about 5 minutes to see if it would stop on its own and it didnt. I attached an image of the setup. If needed I can take video of the bug in action.
