Java applet loading issue when opening content explorer

Hi,

We are in the process of upgrading Rhythmyx from 6.5.2 to 6.7. We use IE8 to access both environments. Recently, there is an error message regarding java applet loading after I use IE8 login 6.5.2.

basic: Loading Java Applet …
basic: Removed progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@186d4c1

It happened only to my machine. I believe it is a local issue. I tried to clear the browser cache and java cache from control panel. But this doesn’t quite work.

However, I can use Firefox to open content explorer in 6.5.2 on the same machine.

Is this related to the java cache? If so, what is the proper way to clear it?

My JRE version is 1.6.20. Thanks

I have found a proper way to clear the java cache. In windows xp, the folder locates at Documents and Settings&lt;username>\Application Data\Sun\Java\Deployment\cache\6.0. After I manually deleted them, the error was resolved. For some reason, the delete cache from java control panel didn’t work.
