This problem has appeared recently. I cannot find a permanent fix. Loading TMG, the Tag Box shows 'Filtered' in red. On examining File>Preferences>Tag Box 'Show non-primary events' is not ticked. I then tick 'Show n.p. events', Apply>OK, then for the session 'Filtered' is not evident. On shutting down, then reloading TMG, 'Filtered' re-appears, and I have to repeat the above sequence to clear the problem. I have been using TMG for years, and never experienced the problem before. Helpful suggestions will be greatly appreciated! Pat Dunbar
