Change mouse cursor over scrollpane?

1

I am using the following code to switch cursors when I mouse over my scrollpane but doing so I loose control over the scrollbars, is there a way to detect if you are over the scrollbars and then turn the cursor back to it’s rginal shape or continue using the scroll bars somehow? :}


this.zoom_in.onPress = function() { 
	 var zoomin = false; 
	 pictures.onRollOver = function() { 
		 zoomin = true; 
		 Mouse.hide(); 
		 this.attachMovie("mag_in", "cursor_mc", this.getNextHighestDepth(), {_x:this._xmouse, _y:this._ymouse}); 
	 }; 
	 pictures.onMouseMove = function() { 
		 this.cursor_mc._x = this._xmouse; 
		 this.cursor_mc._y = this._ymouse; 
	 }; 
	 pictures.onRollOut = function() { 
		 zoomin = false; 
		 Mouse.show(); 
		 this.cursor_mc.removeMovieClip(); 
	 }; 
	 pictures.onMouseDown = function() { 
		 if (zoomin=true) { 
			 if (pictures.content.myLoader.scaleX>=1600) { 
					this.zoom_in.enabled(false); 
					bgSound.start(); 
			 } else { 
					pictures.content.myLoader.scaleX *= 1.5; 
					pictures.content.myLoader.scaleY *= 1.5; 
					trace(Math.floor(pictures.content.myLoader.scaleX)); 
			 } 
			 pictures.invalidate(); 
		 } 
	 }; 
};
