Yes maybe this is the reason. On the other hand, the logs do not
imply that. getCodeBase() gets the proper host and not the proxy.
Perhaps internally it thinks that the applet came from the proxy.

The strange thing is that it did not happen in NS 2.0. I'll send a
bug report to Netscape and hope that someone stumbles accross it, given
that they get a thousands of mails per day.

Thanks again -- Tom
