Thanks Phil, I use google all the time, but didn't think of it to do a search
of newsgroups!
I was wondering why Asteroids only had INV X listed on spies, now that I see it,
INV XY together seems more sensible.
When I get an Asteroids board I'll try it out, it looks good. I'll post what
happens here on the list when I know.
Best regards,
Marc
