I have set up several Mint installs for about a dozen elderly people. The only problem I ever have with their use of linux is that some of them lose the Panel Icons and accidentally change positions of them.
In Gnome2 I can lock down the panel, once it's set up to my liking, by:
Put a check in "Locked Down"
How can I achieve the same in MATE?
(If anyone knows the answer for Cinnamon as well, I'd greatly appreciate that as well. I haven't yet decided on which WM I, or my elderly friends, prefer.)
