Tried running poisson1d.pf, loaded straight from the “Files” menu with no modifications. The script runs fine but does not display the output in graphical form. Command “graph quantity=u” is the very last thing in the script. In the results window I can switch between the log and “u” as the results options, but cannot see a graph. Clicking on the “Download to new web browser window” button does absolutely nothing. I have turned off popup blockers, tried with both Firefox and IE9, same deal. I am assuming that this is some Javascript security setting I need to adjust, can’t figure out which one. Thanks for any help you can offer.
