>>What version of VFP are U using: 3.0 or 3.0b? I remember seeing a message on another board concerning problems upgrading to 3.0b when 3.0 was still on the PC. I hate to say it, but, MS would tell U to re-install VFP. htwh. Steve

excellent comment - Unistall. I forgot to uninstall once and some dirty files were still hanging around after I installed 3.0b...
