I have this at work all the time. We have a process where we try to guide the user to doing the right thing using a couple of dialogs.
Support gets questions all the time from users which just clicked arbitrarily on the dialogs without reading (we can tell by their questions), leading them into a state they don't want.
At this point I'm seriously considering to replace the dialogs with an interactive text adventure-style thing.
That's because too many sites use dialogs to show of new features or whatever.
Meanwhile I am trying to keep what I was trying to do in my head long enough to put it into the app. I cannot read the dammed popups or I will forget what I was trying to do.
