Hi there, I have installed a software from [Processing.org](http://Processing.org) and it is responding the way as described in the text book. After installing the software, click on the File button, then Examples then Drawing then double click Continuous Lines. A pop up box will appear in that box click the Run button . As soon as click the Run button, a new window will pop open running the example. But in my case, as can be seen in my attached screenshot, just a blank new window pop up only without running the example !!!

I need this fixed before my classes start later this month, pls. Thank you very much 💕

Hey  
you have to hold down your left or right mouse button to paint 🙂

You can see it in the code here:

```auto
if (mousePressed == true) {
  line(mouseX, mouseY, pmouseX, pmouseY);
}

```

Hello,

It is not broken.

You need to use the mouse on the sketch window for input.
