Windows XP Adobe Acrobat Pro 9 with the latest updates
This is one of my user's machines. They have basic user rights, non-admin. Opening a PDF file renders the document, but with a dark overlay. It is also missing every other page on every document the user tries to open.
What I've done: Repair install of Acrobat - No change
Uninstall + Reinstall + Updates - No change
Run acrobat.exe as Administrator with my credentials - PDF opens with NO issues.
Transfered PDF to another basic user, who opened it with no issues.
