Hi,
I'm a very very NOVICE to java.
I have mixed to examples from
Steven Holzner's "Learning by examples".
And it works fine if I dont put
the string "_self" in the URL method.
Reading www.javasoft.com this should work. Am I
doing something completely foolish?
I want to keep the frame showing a new
document.
And one more thing. Does anybody
know why "some text" in method newpopupmenu does appear using
netscape but won't appear using MS Explorer 4.0.?
TIA
Poul

I tried it out but failed to notice a main() in your main
class popupx.
Henece did not compile
