I've been experimenting with the general layout of the desktop, and all was well until I moved the panel to the right-hand side of the screen. Auto-hide was on at the time.
I've moved it several times before, without a hitch.
The only thing different this time was that I had Skype running in desktop-share mode, and it had a thin red line (pun unintended, but it fits) around the screen's perimeter.
This line prohibited me getting the mouse close enough to the edge to auto-show the panel.
I stopped Skype, and was able to display the Panel normally again.
I did the same thing again, but this time it didn't reappear, and is now definitely AWOL (after rebooting).
The least I would like from this is to retreive the layout and settings of the applets.
Getting the panel back would be even better.
Thanks for any ideas on this isssue.
