Thanks, Dave... The work setup you describe is in principle comparable to what I do: Having two shell windows open, one running an editor, the other for jconsole; reloading the script to check the changes made. But my guess is (as your's) that I'll need Java for the "plot" examples. Will try installing a newer Java version to see whether it makes a difference. Will take some time as I don't have a cable connection in that place, and wireless isn't yet installed on my machine (but that's a different story).
