java security error

Had some lectora courses (publsihed with java in) working just fine when people had Java 1.6.15 on their computers. Many of these people have updated their java to the latest 1.6.22. These people now get the error message


Security Error, unable to send request.

This course must be loaded from the system that the data is submitted to: access denied (SocketPermission 10.3.111.9 resolve)


Any suggestions how I can correct the problem? By the way, re-publishing the courses with javascript title manager instead is not an option.
