I'm getting deeper into the scripting stuff and it is 
impressing :-)
But now I need some more help... 
Having made some stuff move, like the exelent car example 
I want a way to make those things start and stop 
when I click on them. 
So I make a script for the car that starts the driving 
script on mouseUp. But now I want the car to stop.
There is no way to test if the car driving script is 
running ... 
Must I make two different buttons :-( Or where in the system
is the place to add a test for this kind of thing ?
