| I have a fresh new installation of IDL 7.1, in a 32bits Ubuntu 7.04 Intel QuadCore Platform.  When I start the help system (either with idlhelp from the system or with ? in IDL) it opens a window and says
127.0.0.1 could not be found. Please check the name and try again.
And that's all (the window remains open, but white).  My system is well configured, I can ping to 127.0.0.1 or digg to it also. 
 
Somebody can help me?  Thanks,
