I've added lecture 10 slides, and a corrected version of the lecture 9 slides (thanks Elvira), plus a new version of the Guide to Clawpack slides. I'm hoping the new version of Firefox will allow those embedded links to work. Before they will work you have to do as suggested in my email of 22 October.
Please let me know if the links don't work. I'm not sure I can do anything more about that, but at least it will save me the bother of attempting to make new ones :(
