Static bodies in Fisica

Hi,

I am using the fisica library to create a game in which I have to define a set of boundaries with FBox. The problem is I am not able to disable the mouseDragged function (the player can move the boundaries, so the game is currently pointless).

Is there a way to fix this? I need to use Fisica because it makes the coding of collisions much simpler and I am a beginner at coding,

Thanks!

import fisica.*;
FWorld world;
FCircle circle;
FBox rectangle;
FBox rectangleh;
FBox caja;

ArrayList<FBox> rectangles = new ArrayList<FBox>();

void setup() {
  size(2000,1000); 
  smooth();
  
  
  Fisica.init(this);
  
  world = new FWorld ();
  world.setEdges();
  world.setGravity(0,0);
  
  int i = 0;
  while(i < 100){
    rectangle = new FBox(random(2,50),2);
    rectangle.setPosition(random(0,width),random(0,height));
    rectangle.setRestitution(1);
    rectangle.setDamping(0.01);
    rectangle.setStatic(false);
    rectangle.setFill(255);
    rectangle.setStroke(255);
    rectanglesh.add(rectangle);
    world.add(rectangle);
    i++;
  }
