IE8, IE9, Adobe Acrobat X
Issue: IE error when presented with simple local pdf links
These choices appear differently in micro-version changes of IE from MS, so try them all in order to get rid of the errors:
Modify Tools -> Manage add-ons -> [choose to display All Add-ons] -> Microsoft
Click on the Microsoft header item and click on Disable All
Modify Internet Options -> Advanced -> [Security section] -> Enable DOM Storage
Uncheck this box if it is checked
Modify Internet Options -> Advanced -> [Security section] -> Do not save encrypted files to disk
Check this box if it is not checked
These changes will ensure that the Acrobat toolbar displays like it did in Acrobat 9 and ensure that you don't foul up a print job by printing the pdf before you actually have it on your local machine:
To make the Acrobat 10 plugin show the control tools automatically,
start Acrobat Reader via the Start Menu, go to Edit -> Preferences,
click on Internet and un-check "Display in Read Mode by default"
and un-check "Allow speculative downloading in the background"
to make sure you have it all before it is shown to you.
