If a fader is exactly set to 73% and you click on it to see its value, it does increase a bit to 75%. Usually it never does that when one clicks on it to see its value, but 73% will cause it to rise to 75% and you have to slide it back. Doesn't occur with any other value so far but I haven't checked every single value.
I don't know why it wasn't developed the way that it shows the value anyway just when you mouseover. Especially when looking at tiny dots inside the MSEGs a click that is just a bit too far from the centre will cause a value shift. Maybe you can implement that in an update?
