    int screenWidth = 600;
    int screenHeight = 400;
    int nsqr = 40; // Full length of sides
    int hsqr = nsqr/2; // Half length of sides
    int xcoor = screenWidth / 2;
    int ycoor = screenHeight / 2;

    public void drawQuad() {
        GL11.glColor3f(0.5f,0.5f,1.0f);
        GL11.glBegin(GL11.GL_QUADS);
            GL11.glVertex2f(xcoor-hsqr,ycoor-hsqr);
            GL11.glVertex2f(xcoor+hsqr,ycoor-hsqr);
            GL11.glVertex2f(xcoor+hsqr,ycoor+hsqr);
            GL11.glVertex2f(xcoor-hsqr,ycoor+hsqr);
        GL11.glEnd();

    }

    public void detectMouse() {
        if(Mouse.isButtonDown(0)) {
            xcoor = Mouse.getX();
            ycoor = Mouse.getY();
            drawQuad();
        }
    }


Basically, when I click the left mouse button, it should draw a square (40x40. Mouse pointer at the center of the square).

The location when it comes to the x coordinate is fine; however, at the y coordinate, it's all messed up.

Let's say that if I clicked at the lower half of the screen, the square will appear at the upper half like a mirror.
