PDFs Opening in a Separate Window
If you find whilst reading a title online that each page opens up outside the browser, please open Adobe and go to Edit>Preferences>Internet and make sure the option ‘display PDF browser’ is enabled.

Blank Reading Pane
There is a bug within Adobe X which doesn’t allow users to read embedded PDFs whilst using Internet Explorer 8. The current solutions for this are to downgrade to Adobe 9 or switch to a different browser such as Firefox or Google Chrome.
**Adobe released a patch for this in February 2011 so users still experiencing this problem should upgrade to the latest version of Adobe.
If you are having problems activating the read out loud feature online, please download the title and it should work as normal.
