Thank you for finding a bug on the Processing.js website, or having a change request you'd like to see implemented.

The Processing.js website is not under active maintenance at the moment, lacking developers that have the time to work on it. As such, any bug you find might take a long time to get a fix. However, if you're interested in fixing things yourself, I (Pomax) will be more than happy to review your suggested changes and merge them in if they fix the problem you were having without introducing problems due to side effects your code might have.
