Installed Lineox 4.0 Enterprise Linux

I finally installed one of the Red Hat Enterprise Linux (RHEL) alternatives, Lineox. Installation went very cleanly, basic operations worked well. After a while, I had two lockups occur in the latest release of Mozilla Firefox 1.0.6, something I have not seen on other systems. Response in Thunderbird was also sluggish, but did not appear to be hung. Will have to investigate both systems again to see if it was a one time thing caused by my network or if it was a real bug in Lineox or Firefox.
