TypeError: bad argument type for built-in operation

Steps to reproduce: 1) Open up any dna that contains windows on a wall. 2) Hold down shift and right click on a window. You'll be given a star-like option to choose between different window layouts. 3) While you're able to alter the layouts of the windows with the numbers, if you were to move your mouse back to the middle to cancel out the operation, the program will immediately crash.
