I agree that analog's built-in DNS lookups aren't the right solution for most people running it regularly -- but they should still work right. I'm very confused about this, because I can't reproduce it on Debian Linux or on Solaris 8. Here's one thought. If you run analog a second time, does it fail at the same place, or does it resolve more names the second time? I'm wondering if the lookup which I've timed out is somehow blocking any more lookups. Compiling with -DNOALARM is also a good experiment for that theory. Of course, if anyone wants to take the time to step through a debugger and see what the DNS calls are returning, I would be very grateful, but I'm not going to ask anyone to do that because it's a bit of a chore. -- Stephen Turner, Cambridge, UK http://homepage.ntlworld.com/adelie/stephen/ "The question of whether a computer can think is no more interesting than the question of whether a submarine can swim."
