I too had your problem but just fixed it by uninstalling the version 9 reader and installing version 8 instead. The pdf files I was trying to view on the internet work just fine with that version and it doesn't automatically try to bring up my standard ver 6. You can still download 8 at adobe's website on the following http://get.adobe.com/reader/otherversions/.
I hope this helps.
I had the same problem and this worked GREAT!!!!
Thanks SO MUCh for your help...
