I downloadeded Opera 7.02 + Javascript (12MB) for windows.
Made Opera my default browser. If I want to use Java script applications (for instance naming a date for booking a flight)The functions dont work there.
In: quick preferences and preferences, Java+ javascript are enabled.

Could not copy the Javascript error message(?) but typed it out as good as I could.

Name type error
Message: statement on line 50: expression did not behave to a function or an object: ns_33.addBehaviour
Backtrace: line 50 of linked script (http://www.etc.) ns_33.addBehaviour
Line 52 of linked script (http://www. etc.)ns_pixelURL += "&ns_p=" + ns_12();

With explorer browser I have no problems with the same Java business.

Hoe do you advise me to handle this problem in Opera?

Found the problem...!

In Opera we easily can get rid of POP-UPs with preferences. That preference was activated by me.

If that's activated, sometimes problems with some Java applications start. So the best way to solve those Java problems is, to de-activate the anti-pop-up preference.

Have you checked your JS with Mozilla? Mozilla is excellent for JS debugging.

This is probably a good spot to bring up something that a lot of people have confused. JAVA and JavaScript are two very different things.

The big Opera download that hermanjohann mentions gives you a JAVA Virtual Machine so your system can run JAVA applets. JAVA was originally created by SUN Microsystems.

But JavaScript will run with just the basic Opera download. It was originally created by Netscape and given the name "JavaScript" in an attempt to piggy-back on all the media buzz that JAVA had generated at the time. And people have confused JAVA and JavaScript ever since.

In hermanjohann's case, we are talking about whether a JavaScript will run or not - and that has nothing to do with a JAVA application.
