NIS System Tray icon missing
It appears that the latest update to NIS which arrived yesterday has caused the system tray icon to vaporize.
Windows XP SP3
Microsoft Security Center reports that NIS firewall and AV are running. Clicking on NIS in Programs does nothing at all.
I have searched back and incorporated suggested fixes proposed by a thread from last November. When I deleted the entried to the registry that had been suggested, the icon did reappear after rebooting. However on subsequent reboots it was gone again and even deleting those two entried had no effect.
Yesterday, the IE8 update was also installed.
This issue pertains only to my desktop. The notebook is operating normally.
