Thomas,

It works fine for me, but I am using Graphviz 2.26.3. You can get it from here <http://www.graphviz.org/pub/graphviz/stable/macos/snowleopard/graphviz-2.26.3.pkg>.

When asked to produce the DFA, GraphViz pops up a message like "DOTxxxx.out could not be opened. GraphViz cannot open this kind of file." The message is then repeated for the ".in"-file.
