Installing Netscape 7.1 on SuSE 8.2

I have been trying to install Netscape (following the instructions). When I type ./netscape-installer form the installation directory (as the instructions, um, instruct) I get the following message. Xlib:connection to ":0.1" refused by server Xlib: Invalid XDM-AUTHORIZATION-1 key (failed by comparison) Gtk-WARNING **: cannot open display: :0.1 What does this mean and how do I fix it. I have installed netscape before (on Mandrake 9.0) using this method, and I have never seen this error before. What do I need to do to fix this. Thanks, -=Thinker
