Hi guys, it seems there is an issue on version 4.4.1 with the fullScreen(SPAN) command, I get the following error, thank you.

Hi @hbarragan, thank you for reporting this issue! I suspect it is similar to this one: [Using `Runtime.getRuntime().exec` results in `Cannot run program "": error=0, posix_spawn failed` · Issue #1044 · processing/processing4 · GitHub](https://github.com/processing/processing4/issues/1044)

There is already a draft fix for it, so hopefully we will have it fixed in the next beta!

hi @stefterv, now the full screen works. There is another issue related to performance when drawing a group of images on top of each other (no transparency) which are moving as a group around the screen using the image command on the draw(). Version 4.4.1 works well, but 4.4.4 makes interaction impossible much like a step by step jumping. I am testing with the same code, which is straight forward, just presenting here an excerpt:

```auto
for (int z=0; z< html_source[j1]._images.size(); z++) {
   int tW = ((PImage)html_source[j1]._images.elementAt(z)).width;
   int tH = ((PImage)html_source[j1]._images.elementAt(z)).height;
   image((PImage)html_source[j1]._images.elementAt(z), lpicx[j1] + l3, lpicy[j1] + i4);
}

```

Thank you!
