Glenn, I have been getting repeating downloads with 1.71UE01. Could you try this site:
www.ci.tucson.az.us/dsd --> Ordinance & Codes --> 2000 International Building Code & _local amendments_. This is a 63KB .pdf file and when first download ends, screen goes black, and download starts all over again. Also, as with 1.71, a google search with 50 results per page selected will not give a full page. Roger Turk
