I did clear Java and browser  caches but still had the same issue. For what it’s worth, I thought I tested this with the previous release and it was working.  I can’t be sure though.

 That's odd, as this was fixed in the latest Webmin release.

Make sure all the caches in your browser and Java install have been cleared, in case an old version of the JAR is being cached.

Recently upgraded to Usermin 1.600 hoping to be able to use the File Manager without editing my security settings.  I?m still getting the Pop up warning that ?Java security settings have prevented this application from running. You may change this behavior in the Java Control Panel.?

I know there has been discussion here in the past about fixing this through the Java Control Panel by including the Webmin URL in the list of exempt sites, but I do not have the ability to make that change on my corporate machine.

I have cleared both my browser and Java Cache files.  Am I missing something?
