right click, ClosestPoint, arithmetic functions combinations
In input fields (including object settings), after making a selection of a text, right-mouse-click doesn't open the menu with editing options.
If I define two functions using f(x)= and g(x)=, when I attempt to define the sum (or any other arithmetic combination) function using (f+g)(x), the sum of f and g is multiplied by x.
In the attached file, the ClosestPoint command sometimes doesn't seem to correctly identify the point on the curve closest to the point on the circle. Just click GO and observe how point C is defined as point A travels around the circle.
