Hi Victor,
Thanks for your reply. It does not appear to be a browser issue. It appears to be a clearpass local account issue. I created a test account with the same permissions and it works fine. My coworkers account also works fine. My account for some reason stopped showing items in the Access Tracker. Tested on both Windows and Mac in Safari, Firefox and Chrome.
Everything was working normally a week or so ago, when I last needed to look at the tracker.
There is an update to 6.6.10 which I will probably install tonight and see what happens.
