I'm working on a project which requires me to draw in the control window, then save the images out using saveFrame. I'm unable to draw in the control window because i can't seem to get the control window to stop updating (setDrawBackground not working??)

here's the basic outline, thanks in advance

2. import controlP5.*;
3. ControlWindow controlwindow;
4. ControlWindowCanvas cc;
5. ControlP5 controlP5;
6. 
   
7. void setup() {
8.   size(1024, 768);
9.   controlP5 = new ControlP5(this);
10.   controlwindow = controlP5.addControlWindow("controlP5window", 100, 100, 400, 768);
11.   controlwindow.setBackground(color (0));
12.   controlwindow.setDrawBackground(false); //this not working?
13. 
    
14.   cc=new EmpCan();
15.   cc.post();
16.   controlwindow.addCanvas(cc);
17. }
18. 
    
19. void draw() {
20. }
21. 
    
22. class EmpCan extends ControlWindowCanvas {
23.   public void setup(PApplet theApplet) {
24.     theApplet.background(0);
25.   }
26.   public void draw(PApplet theApplet) {
27.     
28.     //create an image(from processing site)
29.     PImage img = createImage(66, 66, RGB);
30.     img.loadPixels();
31.     for (int i = 0; i < img.pixels.length; i++) {
32.       img.pixels[i] = color(0, 90, 102);
33.     }
34.     img.updatePixels();
35.     //add it to draw
36.     image(img, 17, 17);
37.     //add it to canvas
38.     theApplet.image(img,0,0);
39.     theApplet.image(img, theApplet.width, theApplet.width);
40.     
41.     //draw ellipses in the Control Window(NOT WORKING)
42.     if (theApplet.mousePressed) {
43.       theApplet.fill(255, 100, 0);
44.       theApplet.ellipse(theApplet.mouseX, theApplet.mouseY, 20, 20);
45.     }
46.     
47.     //draw ellipses in the main window(WORKS)
48.         if (theApplet.mousePressed) {
49.       fill(255, 100, 0);
50.       ellipse(theApplet.mouseX, theApplet.mouseY, 20, 20);
51.       
52.     }
53.     
54.     //this doesn't work either?
55.   }
56.   public void mouseReleased(PApplet theApplet) {
57.     saveFrame();
58.     println("yay");
59.   }
60. }
61.
