My blank viewer problem, was related to now being prompted to update Java. It appears starting with update 17, The Java runtime introduced a feature to consider itself old and out of date as of 05/16/2013. It is essentially a built in expiration. So that means our users on version 17 have started to receive this prompt. There doesn't seem to be easy way to suppress. Once a tested version of java is pushed to our users, we don't want them upgrading there java. How do you stop Java from wanting to update itself?
