>It is fascinating how a solution very often comes when you get away from the problem. When I posted this question I was in the office working on a very complicated solution. I spent more than an hour testing various approaches. Nothing worked. But I learning some things about jQuery (good thing). Then it was time to go home. While driving home the solution came to me as a very simple and straight forward. So my suggestion: get in the car and drive around when you have an unsolvable problem :)

I remember I was thinking about a problem while driving my son to WITS. I got so absorbed into the problem and solution I was figuring out when I noticed only after I already passed the street I was supposed to turn. So while I did figure out a solution I lost about 12 minutes driving wrong direction and finally making a U-turn although I don't think it was allowed...
