In order to see and hear the pages on this site as they were intended, it is recommended that you install the latest versions of either Netscape Navigator or Microsoft Internet Explorer - both available free to download for Macintosh or PC. Earlier versions will allow some features to work but may be unsuitable for sound and some aspects of visual presentation.
	Treeline-online also uses the latest version of Quicktime - an Apple product for the development and delivery of multimedia. A software plug-in is provided for your internet browser that enables a quicktime movie to be played over the web on your computer. Treeline-online has several sound-only movies which will only work with this plug-in.
	The link pages are designed to assist in the downloading and installation process. Further information is available at the developers own sites along with links and examples of how to make the best use of your software.
