Wait! Don't tell me...

A high school friend of mine just sent me an IQ test. Still haven't figured it out yet. I'm posting the rules and the URL. http://freeweb.siol.net/danej/riverIQGame.swf
Click on link, and then click on the big blue circle. Use the rules below. This is going to do your head in, but it can be done. Apparently this is an IQ test given to job applicants in Japan: "Everybody has to cross the river".
The following rules apply: Only 2 persons on the raft at a time
The father can not stay with any of the daughters, without their mother's presence
The mother can not stay with any of the sons, without their father's presence
The thief (striped shirt) can not stay with any family member, if The Policeman is not there Only the Father, the Mother and the Policeman know how to operate the raft
To start click on the big blue circle on the right.
To move the people click on them.
To move the raft click on the pole on the opposite side of the river.
