To find out the version of the web browser you are currently using, go to the Help menu and select the About item.

For Internet Explorer,
you need to have the Java Virtual Machine component installed. To check this, go to the menu item "Tools" and select "Internet Options...". Click on the "Advanced" tab and scroll down to see if "JIT Compiler For Virtual Machine enabled", or similiar type statement, is ticked. If it is not, then tick it and install the necessary component. if there are no Java options at all, you will need to install Internet Explorer with the "Customise" option and make sure that you select the "Microsoft Virtual Machine" option. If it is already installed and you still only see a grey box where the panoramas should be, reinstall the Java Virtual Machine component. Unfortunately you need to reboot your computer after installing it to get it to work, but there are many other web sites that require Java too, so it really is worth doing. (You must be an administrator to install Java if you are using Windows NT.)

For Netscape,
go to the "Edit" menu item then select "Preferences". Click on "Advanced" and make sure that the option labelled "Enable Java" is ticked.
