java permissions for ARIS ?

Hello,

surprise this morning for our students using ARIS for a project, an error occurs regarding java permissions... "message "Missing Permissions manifest attribute for arisloader.jar"

After different tests, we conclude that we have to reduce the java security level to authorize the application (to "average" level, the lower one proposed in security tab of java setup).

And unfortunately, for some users (not all), we have still an issue. Hereabove the java trace in these cases not solved..

thanks for any help
