Is there an ex11_lib.erl version 3.2 ? I have 3.1 but a 3.2 is mentioned in source code that I have seen... By the way, ex11 works like a charm on Mac OS X, out of the box so to speak. http://www.kvamme.se/Aphasia/ex11_on_osx.gif On Ubuntu there is an auth problem. I have tried xauth and xhost without success. /Sten Kvamme
