4 years ago There's a more recent version available here: https://computinged.wordpress.com/2019/07/22/beta-release-of-new-jes-jython-environment-for-students-now-available-media-computation-for-python-ide/
I have not seen this bug before, and I don't have a Linux box at hand to test with. See if this works, please, and let me know.
