After all, far too often in the IT world it's PEBKAC.

Just dealt with one today ... though in fairness it's often not their 
fault. Too few apps give decent visual feedback about changes made by 
abberant clicks or accidental keyboard shortcuts - MS Word is a 
nightmare for this, as is any email program that lets columns be 
hidden/reordered by clicking on the column heading (though that one 
could be considered fairly visually obvious "if brain on").
