If you have Windows 8 laptop with touch screen then you might run into an issue with your Adobe Reader XI like I did. Your Adobe Reader is configured (by default) to detect if you are using a touch screen and if you are then it will not show the scroll bars.
To show the scroll bars by default go to "Edit > Preferences". There select the "General" category and for "Touch Mode" select the option of "Never".
