MOVING PANORAMAS? RPG XP

Basically one of my characters is on top of a moving truck which is being pursued by monsters, and I was wondering if there was a script out there to make the panorama's move. I gave dubealex Parallax Background script a shot but during test play the game would keep freezing. So I'm just asking if there is any alternative scripts or even better would it be possible doing it through clever eventing?

Thanks pal, but dosn't seem to work for me
