RHE What?? RHEL 4 or 5? ES/AS/Workstation? On VPS??? Do the buttons work on other websites?? What browser are you using?
I tried it with Firefox, Konqueror, and Epiphany, and all worked fine. Even went to a Windows box and used IE6, IE7, and Firefox there, and it all worked. You click the button, it disappears, then you can download software.
