Java Plug-in throws JScript "Object Expected" error

I am trying to embed an applet in a page using the object tag. When the page load, I get a JScript (not JavaScript) runtime error saying "Object expected." It is nothing like your regular JavaScript error dialog. It looks more like a JS alert pop-up, with no line numbers or anything else. The applet runs properly though.
All machines I've tested on are Win2K. I get this pop-up in some machines but not in others. It is not related to browser settings.
I am wondering if someone has ever seen this problem before and, if so, if they were able to solve it.
Thank You,
Heitor

Just to clarify it more. It is also not a JavaScript issue, since I stripped the page of all the code and just left the HTML code for the object tag in there. Also, the applet is not calling any JavaScript methods or triggering any browser events.

can u pleaze post ur html code here?
also , did u try on Netscape browser? (may be on newer versions)?

Here it goes....
Netscape is not supported by my client.

I know it has been a long long time. Did you ever resolve this issue? I'm seeing the same issue on some of my systems.
