It is different. The end user flails away at the keyboard and mouse,
entering
text where numbers should go, and dividing monthly pay by Fred. They
also
occasionally delete files at random "to clean up their disk", and then
complain
that your program "won't work". These actions are rather hard to
predict.

The problem with any "failsafe" routine is: what exactly should it do?
Stop and save the changes? Roll back to a previous state? Assume some
data
that isn't there? There's no way for anyone but the programmer to know -
based
on the exact state at the time of the error. So we're stuck with writing
input validation routines anyway.
