My applet works differently between online and offline.
http://blogfile.paran.com/BLOG_253895/200609/1157419012_DodgeSnowLauncher.html
This is my applet which I made yesterday.
When you click on the link, push the button, and run the applet online,
nothing happens when you click on help - about dodgesnow version 0.1, which is on the menubar above.
However, if you download the html file and run the applet again, you can see the "about dialog".
The dialog is made with the dialog form in NetBeans 5.0, and therefore uses its own layout library.
I want to know why this happens.
Thanks.
