- I ran the repairs to see if the program code had changed.
- I went through the repair logs and they showed that I ran repairs 1, 2, 3, 4, 7, 8, 10, 12, 13, 14 & 18 (in several combinations) but NOT in Safe Mode. So, it seems that one of those repairs breaks these system tray settings.
- And this could be either "policy" issue (repair #12) or a permission issue (repairs #1, 2, 3 ,4). The error mentioned in post#1 of this thread could be related to this "system tray" problem. I.e. due to a permission problem the user could be unable to change those system tray settings.
