We have quite good connections at the university, and we get the Java error there all the time. I have dial-up at home, and I get the Java error regardless of whether I am connected. > I wonder if Mathematica is trying to update some component on startup. > Any internet access would probably occur via Java. In particular, have > you configured your Mathematica to pre-load any software? Nope. But apparently Mathematica itself tries to load some Java stuff on startup, hence the timeout errors. -- Helen Read University of Vermont
