[gui-talk] home network problem

Tue Apr 10 11:00:38 CDT 2007

Bob,

This is very good to know, but I don't think that the old computer is even getting an internet connection, so I am assuming that the problem is different.  I believe the 
problem even exists when the new computer is not active.  Still, I am going to keep your experience in minds as it is likely going to be repeated as VISTA machines 
become more common.
