A phone call from my Mother in Law.
"The internet is broken"
I asked her to describe what she saw and what she told me sounded like a disk failure
Turns out that she had got the left right buttons on the mouse confused and somehow deleted the firefox shortcut on the task bar.
Since she never used computers until about seven years ago I can't really complain but I do wish I could just nip down there (jamaica) every time there is a problem of this sort rather than have multiple phone calls after work.
I have always tried not view very inexperienced users with contempt. Experienced users is another matter entirely ;-)
