heliograph is probably chuckling to himself because he has always suspected the SETI programs of being up to no good. After this little fiasco I think I have to admit that I feel halfway convinced, though I doubt that it was done maliciously. But the result of removing it, so far, is faster performance, no delay when opening Xearth (which used to take 20 seconds to start), and a working Psion.
I think I've done something like 1500 units so I'm not going to feel guilty about calling it a day. If the aliens are out there, we'll have to find them without any more help from me.
