jit.world to jit.pwindow

I created a particle image based on the "Amazing max stuff" YouTube tutorial, which runs through the jit.world object. I want to make it work inside the patch instead of using a floating window. I used the @output_texture 1 attribute to connect it to a jit.pwindow object. Loading the image and displaying it with each pixel as particles inside the jit.pwindow works fine, but the mouse interaction part doesn't work at all. Specifically, clicking on the screen should make the particles spread out from the mouse position, but this isn't happening. What could be the problem, and how can I fix it? Please help!
