NBU Java Admin Console

I run the Java Admin Console from my local machine.  I don't use the Windows Admin Console or jnbSA.  I've noticed that when there is no activity (backups/duplications/restores) if I click on any completed job, it comes up blank.  The console then gives me some sort of timeout error and I have to hit the refresh button.  Has anyone else experienced this?  I've seen it in 6.5.x, 7.0 and now 7.5.0.6.  As long as backups or any other activity is happening Activity Monitor is fine.
