The image, (of the old Venetian harbour of Chania in Crete), should gently revolve. The problem for you I suspect may be due to differences between Sun Java, and Microsoft Virtual machine. I have found that they are different, as when I installed the Sun version, I also had problems.
To remove the Sun Java, I used GoBack to revert to an earlier time.
Can you tell me if Sun Java appears in the "add/remove" programmes in control panel.
