Workaround:

1. void setup()
2. {
3.   size(400, 400);
4.   frame.setResizable(true);
5.   size(screenWidth, screenHeight);
6.   frame.setResizable(false);
   
7.   textFont(createFont("Arial", 48));
8.   fill(0);
9. }

thanks PhiLho, I'll have to remember that fix. I also see that you moved my post to a different forum. Thanks for that as well :) one of these days I'll post a topic in the right forum.

Yes, if I posted a comment each time I move a topic, I would double my message count!
I tolerate Eclipse topics in Programming Questions if it is mostly about some code issue, but export issues are definitively a I&H topic.

Have you read the https://forum.processing.org/topic/where-to-place-threads-and-other-forum-practices topic?
(And thanks for caring to notice... )

Thanks! I took a look at that post earlier but not a close one. But I read through that completely now
