Arima - on the other hand, it confused a lot of people because if you did:
+ Sprite X < 400
-> Do something with Sprite
-> Do something else with Sprite
...they naturally expected the 'else' to only affect objects on the right, and I agree, that's how I think it should work too. However it turned out to be too complicated to get it working like that in Classic. It should be doable in C2 though.
