Web pages don’t look right

This site makes extensive use of Cascading Style Sheets to format the pages. This keeps the page sizes to a minimum for faster download times and means that the pages should be readable in a wide variety of browsers, including mobile phones and screen-readers used by the visually impaired.

The problem with Cascading Style Sheets (CSS) is that different browsers interpret the same page differently. Any browser that conforms to the W3C standards should have no problems with this site. In the real world, this means all browsers such as Safari, Opera and Mozilla should display these pages as we intended. Internet Explorer version 6 and above should also work without problems.

However, whatever your browser is, you should still see all the information – the headings will still be there and everything should work – it just won’t be as pretty.

I get a “That page does not exist” error

Use the search field and enter a word or two on the topic you were looking for

Otherwise, go back to the home page and navigate from there.

Adobe Acrobat (.pdf) files

We recommend that you use Adobe Acrobat Reader version 5.0 or later to view Acrobat files on this site. 

Saving Acrobat files to disk

If you are having trouble viewing an Adobe Acrobat file in your browser, or you would like to have a copy to look at later, you can download the file to your hard disk.


  • Use the right mouse button to click on the link to the PDF document you need.
  • A menu will appear. Choose the item “Save target as…” or “Save link as…”
  • Save the document to your hard drive. You may want to make a note of where you saved it.


  • Click and hold the mouse button on the link to the PDF document you need.
  • After a short pause, a menu will appear. Choose the item “Save this link as…” or “Download link to disk”.
  • Save the document to your hard drive. You may want to make a note of where you saved it.
  • If you wish, you force Acrobat documents to open outside the browser. Look for Portable Document Format under Applications or File Helpers in the Preferences dialog of your browser. Change the setting to handle PDF files with the application rather than the plug-in.

Problems viewing Acrobat files

The first option is to try saving the file to your hard disk and opening it from there.

Acrobat page appears blank

Microsoft has published an article in their knowledge base – Adobe Acrobat .pdf Files Appear as a Blank Window or Frame (Q177321) which offers a number of solutions to this problem.

Printing Adobe Acrobat files

To print an Acrobat file from your browser:

  • Scroll to the end of the document to ensure that it has all downloaded to your machine
  • Click on the Print button in the Acrobat toolbar. Do not use the browser’s print button.

If Adobe Acrobat (.pdf) files do not print correctly, there are a couple of things to try:

  • Download the complete file rather than trying to print from within the browser.
  • People using MS Windows may need to change the settings on the printer driver. Choose ‘Properties’ or ‘Options’ in the print dialog. Look for options that allow you to set fonts to download as bitmap fonts and use raster graphics rather than vector graphics.
