Here's a short list of interface lies....
1) My error message is meaningful and helpful.
Sure. Like, "Can't find file" with no explicit reference ON THE DIALOG as to the the file name you typed in or the path it was supposed to be in, because God knows, we wouldn't want the user to be able to tell IN A SECOND where the problem was. No, let's make the user *dig* for it.
2) It's OK to shove warning and alert dialogs into people's faces.
After all, when we're at a restaruant, don't we *all* want the waiter to interrupt every few seconds with the night's special, warnings about peanuts, and the effect of alcohol on pregnant women. It's just as wonderful and helpful in software.
3) It's OK to make users wait.
Because users care *so much* about your little issues with processes or your inability to put things into separate threads while you keep the interface alive. I mean, when you're in a restaurant, don't you *love* it when the waiter ignores you because they've got something better to do?
4) It's best to steal input focus from the user.
After all, who knows where they'll type? And so what if they're already doing something else, what could be more important than MY little dialog? Modal dialog, of course, because they shouldn't do anything else until they pay attention to ME!
5) We'll help the user by refreshing his whole screen!
I mean, there's just nothing better than the waiter who rearranges everything on the table after you've started eating, just to make sure you have everything and the food is truly fresh! Of course, this couldn't be a bad habit of lazy, uncaring programmers who couldn't be bothered to get the screen or list right the first time before presentation. No. Certainly not.
