I have an Access Database that contains a form with a button to view attached PDF files. I have Acrobat Reader loaded on the computer. When using a computer with XP OS you just double click on the button, and Acrobat Reader opens the PDF for viewing. I return to the database form just by closing Reader. However, on a computer with Windows 7, when I double click on the button to view the PDF the PDF file opens in Reader, but I have to hit Alt+TAB to view the file. Any suggestions?
