When creating Javadoc or viewing an html page with the system default browser I get an exception. I'm using firefox as default browser.
Created attachment 19043 [details] message.log containg the exceptions
It was actually a configuration problem, But this could only be solved be renaming the .netbeans/4.0beta2 directory. Now it works again. It was impossible to change the entries neither by options nor setup I always get the IllegalStateException. So I think this topic has to be relocated, since it seems a configuartion problem. But I don't know how this occured.
