This website has no flash gimmicks; it is designed to be fast to download and easy to use.

Testing

• All pages have been written in validated XHTML 1.0 Strict and CSS 2.1 code to maximise cross-browser compatibility.

• The site has been fully tested with browsers Internet Explorer 6.0/7.0, Firefox 2.0.0.12, Opera 9.25 and Safari 3.0.4 using the MS Windows XP SP2 operating system at screen resolutions down to 800 x 600 pixels.

Optimal viewing

• This site is best viewed at a screen resolution of 1024 x 768 pixels or higher, though it is still usable down to a resolution of 800 x 600 pixels. The resolution can be changed in MS Windows by clicking on the Start button and selecting:
  
  Settings > Control Panel > Display (Windows 98/SE/ME/2000/XP classic menu), or
  
  Control Panel > Display (Windows XP standard menu).
  
  Then select the Settings tab in the resulting dialog box and adjust the screen resolution slider as appropriate.

• Your viewing experience may be enhanced further by:

  • maximising the browser window (click on the overlapping box symbol next to the "x" in the top right hand corner of the browser window)

  • using Full Screen view (select F11; repeat to return to normal view);

  • increasing/reducing text size (in Internet Explorer select View > Text Size and choose from the range largest to smallest, in Firefox and Opera click Ctrl+ or Ctrl- to zoom in/out in steps);

  • enabling Javascript. This website uses Javascript language to display adverts and to monitor site usage. If you have Javascript disabled on your browser it may slightly distort the website layout. Browsers usually have Javascript enabled by default, to find out about checking/changing your settings, click here.

Navigation

• General navigation can be performed by clicking on any of the following:

  • main menu on the left

  • page path 'breadcrumbs' on top bar

  • menu on bottom bar

  • emboldened green text links within central text columns

• All text links to external web pages (and internal pdf files) are marked with emboldened blue text. These links are opened in a new browser window, leaving the APS window open in the background. All other text links open in the same window. Some links are accessed by clicking on images, these are mostly opened in new windows.

• You can use the 'Back' arrow button on the browser toolbar to return to the previously-viewed page. Users can occasionally experience problems using the Back button, depending on their browsers settings. This can normally be resolved by repeat clicking on the button several times.

• A quick way to return to the top of a long page is to press the 'Home' key on your keyboard. Alternatively, click on the 'Back to top' links which have been inserted at intervals on some of the longer pages.
