How do I launch that from the command line? I seem to have erased to
many things in cleaning up the Kmenu!

I will install the package anyway, but how do you define slow? 20 ms? 80 ms?

I'm on a commercial ISP, not the university. So far as I know, I'm
right there on the net. I don't think that there are any ports being
blocked, and I don't know of any filtering/logging going on. I'll ask.
I should know about this if it is happening.
