First of all, this is my first post ever.
I hope this is an appropriate question.

I typed in the code of Try It Out
Framing a Window
on page 771. I ran it under Explorer which
I had upgraded to 1.5 with a download from SUN.

I got the error message
exception: Java.Lang.NullPointerException
Followed by Loading Java Applet Failed.

Now what?
Any help will be appreciated.
