I've just started playing around with Processing and I can't even get the simplest script to work! Please, take a look at the screenshot below.
If I change the opacity value to 255, then I get a fully orange window. If I change the opacity value to 0, then I get a fully white window. However, if I use any opacity value in between, then most of the window stays white and the rectangles on the left are shades of orange. The orange shapes never change even if a close and restart Processing.
