Microsoft JScript compilation error alert on initial load using IE7

882132

I have noticed that a javascript alert window is displayed whenever an Applet is initially launched using IE7.
This does not happen using IE8 (or FF, SF, Chrome, etc).

I thought it was our implementation, but the alert is also shown launching any Applet from the following;
http://java.sun.com/applets/jdk/

There are typically 2 alerts and after pressing OK, the Applets appear to run successfully.

The specific error is;
Alert title: Microsoft JScript compilation error.
Alert content: Expected ')' in regular expression.

I don't always remember this error using IE7.
Maybe it's related to the JRE?
I am currently using: (build 1.6.0_26-b03)

Any solution out there?

I just had a look at the source of two of the pages from the 1.4 section of that page (Animator (1) & ArcTest) & saw some very questionable HTML for the <tt>applet</tt> element, as well as two seemingly unrelated scripts. What do you get for (instead of those), the GIF Animator (the applet form)? It uses <tt>deployJava.js</tt>, which is about the only deployment option that Oracle cares about at the moment.

I get the same 2 alerts when launching the Applet from http://pscode.org/gifanim/applet.html
Is this the site you were referring to?

Yes, that is the one.
