Parallax not working

I see the image with a Book on the left, and it works with the parallax by my side on your website

Sorry but there is no parallax movement in these pictures, indepentently of the speed settings in the parallax widget.
I tried this with several browsers in cas it would be browser independant.

I have found the problem, the speed factor was not correctly set
I have updated the widget, please tell me if it is better now

(ps: the parallax works, just that the effect is too light because of the speed factor problem)

still not working

just checked here
mc3.thei.nl/
with Firefox, and it works

I have tried the Parallax also and it does not work.. I have tried all of the suggestions but no..

It would also be really nice if you added the search back in on the Kunena Forums, looking for information is painfull haveing to go through each page..
