Since you have two topics going on the same exact topic, i'll repeat what i suggested in topic # 2:
Stop using the minified version for debugging purposes.... if your code doesn't work, you should be using the "full" version of jQuery, as the minified version adds a LOT of complexity when trying to figure out what (bad) is going on On Dec 14, 6:03 pm, Henjo <henjohoek...@gmail.com> wrote: > Hi Scott, > > thanks very much for your elaborate writing.
