Hi,
Are you using the plug-in 1.1 for running the applet under NetScape 4.5? If not you have
to get the plug-in 1.1.1 (there is another version of plug-in - 1.1.2 - but thats for
jdk1.1.7B) from Sun's site.

You may also want to try with Netscape 4.51, this is supposed to run jdk1.1.6 vm (incl
swing) without the plugin. But, if you later move to the next version of jdk i dont
think NS or IE support it - you would have to use swing then.

hth,
Vasu
