Hello,
I just got the SUN Java IDE. (Netbeans IDE 3.5.1)
Very very nice, and I worked myself through the tutorial (about making a
colorswitch).

Now, When I compile it gives no errors at all. So far so good.
But when I want to execute, it askes to "set project main class".
The only option it displays is the default project. But the "okay" button
won't highlight.
I cannot select anything else, nor can I roam directories to select
anything.

Can someone please help me out.
I feel kinda silly not even knowing how to start a kind of hello-world
applet. ;-)

best regards,
martin
