This applet shows the Java 1.1.x conventions for
event-handling (click here for the source code).
Consequently, this applet requires a more modern
browser. Some examples are Navigator 4.x (with
SmartUpdate on Windows, 4.0.6 (only) on Macintosh)
and Internet Explorer 4.x.

On Mac also try Cyberdog with MRJ 2.x. Some
tinkering required.
