I have an issue (Processing 4.1.2 MacOS Big Sur Intel 64 bit) in that when I Export Application – **even if I uncheck the Presentation Mode checkbox and compile the application runs fullscreen**. I want it in a 800 x 800 window as I specify in setup() size(). Any ideas why? Not supposed to do this and never used to do this…
