We are not unhappy about invoice choices...it is the doubled layered of the user interface on the left column of the screen 

I have to try to click just right to get the right menu to be uncovered, then I have to click as normal to get to the actual screen I want.       It is VERY difficult to get the mouse in just the right area....too sensitive an interface.....I can't begin to tell you how often another screen opens that I did not want.   I am wasting time trying to navigate to be able to click to the correct screen.
