Hi, I am running a processing sketch by calling it from a JavaFX application…
**public** **class** Main **extends** Application {
**public** pro sketch;
@Override
**public** **void** init() **throws** Exception {
sketch = **new** pro();
sketch.run();
}
Then…
**public** **class** pro **extends** PApplet {
**public** **void** run(){
String[] processingArgs = {“main.java.test.pro”};
PApplet. _runSketch_ (processingArgs, **this** );
}
**public** **void** setup() {
minim = **new** Minim( **this** );
ETC…
}
**public** **void** draw() {
**if** (frameCount % 100 == 0){
System. _ **out** _ .println(“In Draw:” + frameCount);
}
ETC
This works well for me on two Windows PCs I have but a third one, which is not as powerful but not very old, the processing sketch never draws, the canvas appears but then just nothing. I can see code in setup is run when I add lots of logging but in the Minim( **this** ) “this” is null as if the sketch hasn’t had time to load itself properly.
If anyone has any suggestions that would be great but are there other areas I can check for internal PApplet logs or perhaps some PApplet methods I could call to check its state.
Any help much appreciated.

I decided in the end this was just because it was a rubbish PC!
