Could you please to advise me how to run enclosed applet in Netscape=AE
Communicator 4.04=20
It works fine in appletviewer but not in Netscape.
I am just trying to read from text file which is going to be on host in
the same location as an applet.
I am not trying to write or read something that does not belong to me.
Just my own file
Why there are such difficulties?
