Windows XP users:

XP and Java.
Microsoft has recently stopped support for Java from Windows XP. Users with new Windows XP desktops who visit a Web site that uses Java will find that the pages won't open fully, and in some cases won't open at all, without a separate download.

Why ?
Existing versions of Windows contain a chunk of software code, called a Java Virtual Machine, or JVM, that allows the Internet Explorer browser to execute Java programs. Some XP operating systems (service pack 1a) do not have the JVM included.

Solution.
There is an automatic download and install of the Sun JVM here:

just follow the simple on screen instructions.
