hey, I use flash mx, but i’ve been staying at a friends house lately who uses mx 04, i was wondering a few things like…how come this movement script works in mx, but not mx 04…  
placed on a mc that i want to move around

[AS]  
onClipEvent(enterFrame) {  
if(key.isDown(key.RIGHT)) {  
this.\_x += 5;  
}  
else if(key.isDown(key.LEFT)) {  
this.\_x -=5;  
}  
}

[/AS]

so why does this work for mx, but not mx 04
