	Web Tools

A web browser is used to display help pages, screenshots after they have been created and Presentations. On Linux systems there is an internal browser based on HV3 or a default external browser is usually set up when first running the program:
Windows: the default hander for html files. This is found from the registry, looking for either 'HTTP','http' or 'https' in the 'HKEY_CLASSES_ROOT' part of the registry and extracting the 'shell/open/command' information.
Mac OSX: the 'open' command which will open the appropriate viewer for the file type
Linux: whichever of the browser: firefox,konqueror,mozilla or netscape, is found first

The Preferences option Browser/web tools (in the Tools folder) has a menu option listing possible browsers. If this does not work then it may be necessary to enter the full path name of the Browser executable which will then be used in preference to the menu selection.

The internal browser is always used for Presentations and external browsers are used for access to coordinate download sites. The Preferences window has a Use internal browser option which to use for help pages and screenshots. Note that the present version of the internal browser (CCP4mg 1.1) does not support Javascript and so is poor at presenting more sophisticated web sites.

The Preferences window also lists the URLs for the coordinate download sites - these are not expected to change but are there just in case.
