Under Number Slider > Right Click Menu > Values when double clicking on Min, Max, or Val, these show a text input box to input a new value. At first, this would allow me to type in a value and then press commit. When I reopened Rhino, it would only show the input box for about 1 second then cancel. I tried restarting Rhino and now it only shows the input box for 1/10 of a second. I tested this in a fresh project and it exhibits the same behavior. There is a workaround which is to use the Edit menu.
