 When entering the screen setup wizard for the first time, the bottom right
 arrow is not visible. It is off screen to the right. While it can be moved
 up and left and positioned to the screen dimensions, this results in the
 wrong screen size.

 If the screen setup wizard is entered a second time, the bottom right
 arrow is visible.

 The reason for this behaviour is because the image for the arrows get
 loaded in a background thread and are not ready when the dimensions are
 extracted, resulting is 0,0 size. This effectively positions the bottom
 right arrow with its top left corned as the origin instead of its bottom
 right, resulting in an error in x and y equivalent to the size of the
 arrow image.

 I'm attaching a patch with what I think is a good workaround. When the
 bottom right arrow is selected, it checks for a zero size arrow and re-
 initializes it. On my systems, the arrow was always positioned correctly
 with the patch applied.

 Perhaps there's a way to have the images load in the current thread, but I
 haven't found anything yet.
