No, I didn't touch the registry.
There was an "icon" just to the imediate left of the "clock" upon which I inadvertently clicked. The "notification area" disappeared.
I have no idea what happened.
When the IT administrator logs on to my pc, the notification area is visible. It appears that something in my user profile is amiss.
If I click on systray.exe, nothing happens.
In the "Task Manager - Processes" menu, systray does not appear.
The start-up programs are working, but there are no icons visible
in the taskbar.
Any suggestions ?
