Thank you for your assistance. However, I must say that, as a newbie, I find your comments about CentOS being inappropriate for some kinds of application a little odd. Why should an application built for Linux not work on a distribution of Linux? As an aside, before attempting to install CentOS, my first choice was Ubuntu. But their installer kept hanging somewhere in the middle of the installation process, so I decided that was out. So Ubuntu did not impress me as an option. In any case, I searched around for which build would be most appropriate for me, and nowhere did I come across information that clearly said to me "You really can't or shouldn't run this kind of software on this build". Different distributions came with different philosophies, prices, and advantages. But if any one of them could not run a Linux application, then isn't that build broken? Dave
