The Maplet application will appear in a separate window. It could take a few
seconds to load. (The first maplet downloaded might require a minute or two)
Should you see a message about a package being aborted, just click OK
and update your Java Runtime Environment to version 5.0 update 7 (or
newer). Java can be downloaded from
http://www.java.com/
If you see a Java Security Warning asking "Block potential unsafe
components from being run?" Click either YES or NO; it does not matter.
Do not close this window until you are finished using this maplet.
