I got all the way to end -- the status bar was at 99% and I had just answered end-of-survey demographic questions -- and was told that I didn't qualify and asked if I wanted to try another survey . . .

As far as the child doing the survey thing, I've quit calling my child to the computer until I answer his first three or four questions. They are always either demographics or stuff like whether you play videogames, how many times you've been to the movies, what kind of soft drinks do you like, etc. I've found that he gets kicked out on the early questions at least 75% of the time.
