Rotation

I now changed it to

Bangle.setUI({
  mode : "custom",clock:true,
  remove : function() {
    // Called to unload all of the clock app
	if (typeof PosInterval === "undefined") {
		console.log("PosInterval is undefined")
	} else {
		if (PosInterval) clearInterval(PosInterval);
	}	
    PosInterval = undefined;
    if (drawTimeoutSeconds) clearTimeout(drawTimeoutSeconds);
    drawTimeoutSeconds = undefined;
    if (drawTimeout) clearTimeout(drawTimeout);
    drawTimeout = undefined;	
	if (typeof onDrag !== "undefined") Bangle.removeListener('drag',onDrag);
	if (typeof onLock !== "undefined") Bangle.removeListener('onLock',onLock);
  }});

Now, the loader shows up, but the Listener seems to be still in place.
