>I have to agree with Jim. IMHO, the fewer choices you present the user the fewer opportunities for disaster. Because humans are in-exact by nature, the more specific you make your user be about his selection the less likely he is to make a change to the wrong record. Somewhere along the line the user has to take some responsibilty. I can't prevent every user from making any possible mistake. It's really hard to make your software idiot-proof when there is always a better idiot lurking just around the corner. :-)

And it's not just the idiots - I take it for a known fact that though you can (theoretically) write fullproof code, you can't make it foolproof - but it's just the normal users, who may get quickly annoyed by forever repeating the same sequence of control questions. Eventually, these questions may prove to be worthless, because the users get used to them quickly, and just go clicking the usual answers without giving it much thought.

We've had users who actually deleted some stuff because they answered "yes" to three control questions in a row... and later confessed they didn't read them at all.
