Hi Jason, I gave an example for what does not work here: http://groups.google.com/group/sage-support/browse_thread/thread/17c717e8bfbdd367/b2fdb60e1f33b43e#b2fdb60e1f33b43e
Today I noticed that my old use of .subs(locals()) now leads to an error, too. I could try to copy the notebook to somewhere else, but I don't think this would avoid the "Unable to start maxima" error I am getting. It seems that the upgrade to 4.1. changed something that 3.4 was using, so 3.4 does not work any more. If I install 3.4 again, I suspect that this could break 4.1, so I would get myself into an awful mess, wouldn't I? Thanks for your help!
