hmmm..Opera wanted to download the whole thing before it showed me anything, so I went to Netscape 4.79 and it very politely loaded one page at a time! showed me page one...then loaded page two....and when I asked, it went to the last page...then to page 170 when I changed the # (all this was online...NOT after downloading all 2.7 million bytes)

it all showed up just fine...perhaps your copy of Acrobat has a problem?
Wish I could offer more help, but it just works here...
