Thanks for the advice, I had just read similar precautions in the aforementioned book. I am, however, on a test machine within a private production LAN trying to get a distributed app style simulation software to run so I can help alter it to a client's specs. I want to keep everything as vanilla as possible so I have less to troubleshoot! :) Now, how do I set the DISPLAY (and other variables I had to set for this program) permanently? And do I set them as root, su, or my normal user account? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
