Thanks for the bug report. Are you using Firefox? I knew this happens in FF and couldn't find a fix for it. As for structuralism, the general idea is that it is a way to axiomatize empirical theories using formal logic and set theory. More specifically it postualtes that scientific theories have a typical logical structure, that you should be able to find in theories of many different fields (from physics to biology to sociology). And people have "reconstructed" (i.e. axiomatized) theories from all those fields. So, in a sense, it is like a theory about theories and how they are structured. Hope this helps ;)
