Using the OPERA browser, you may find that on links from the main page, the scrollbar gets 'lost' when
you try to scroll down to the end of the page. If this happens, click on the square 'maximisze' button
for that browser window, and the problem will vanish.
When you click on any link from the main page, what is happening is that a new browser window is
opening. Then when you click a 'return to previous page' link, the new browser window is automatically
closing. However, if you have problems with links on this page, please try the
non-Javascript version
