Can't stop moving the new panorama when I load a new scene

Hello,
I have loadscene_flags="MERGE". I don't have KEEPMOVING ?!
I don't know how to prevent moving the new pano.
Here is the case:

I've managed to resolve it by adding oninterrupt(break);

krpano().call( "oninterrupt(break);moveto(

But I thought that the flag KEEPMOVING was enough
