just a little warning. don't put centerlines in an ass'y of any appreciable size! bob z. is sitting at a machine that is cranking away at 100% processor usage. it's been like this for a while. maybe bob z. didn't do something right or maybe this ROCK FREAKING SOLID MICRO$LOTH box is going down again. bob z. had to reboot once this morning. the wonderful M$ Internet Exploder took the system down to it's knees.
