There have been several solutions suggested in the forums about how to do this. If you use Firefox, you can install an add on called Tab Slideshow. Open each map view in a different tab and then start the slideshow. It will display each tab for however long you set it to before rotating to the next tab. It's easy to install (and it's free.)
Hope this helps!
Thank you for your quick reply. That's pretty cool - it's perfect.
