[as2] clearInterval Problem

[VisuaPix]

I have made a menu, that reads its content out of an XML file.

When you move over the buttons, the scale, and alpha is set to 100.
When you leave the button it is resetted to it's original size/position.

But, if you move to fast over the buttons, they disappear. It's like the file doesn't call the clearInterval:

Here is the code:

code:

---

//Begin of code



a=3

mcBalk=this.attachMovie("balk_mc","mc_balk",0)





mcBalk._x=Stage.width-(mcBalk._width)

mcBalk._y=(Stage.height/2)-(mcBalk._height/2)











menu_XML=new XML()

menu_XML.ignoreWhite=true 

menu_XML.onLoad=function(OK){

	if(OK){

		Menu_inladen(this.firstChild) 

		}

	else{

		trace("No valid XML-file")

		}

	

	}	

menu_XML.load("XML/menu.xml")



function Menu_inladen(data){

	

	aantalMenuItems=data.childNodes.length 

	arrMenuItems=[]

	for (i=0;i<aantalMenuItems;i++){

		ItemNaam=data.childNodes[i].childNodes[0].firstChild

		UrlImg=data.childNodes[i].childNodes[1].firstChild

		arrMenuItems.push({nr:i, name:ItemNaam, UrlImg:UrlImg});

		}

		

		

	for (i=0;i<arrMenuItems.length;i++){

		mc=this.attachMovie("button_mc","mc_button"+i,i+1)

		mc._xscale=50

		mc._yscale=50

		mc._alpha=50

		mc._x=470

		mc._y=50+(i*80)

		mc.obj=arrMenuItems[i]

		mc.obj.mc=mc

		UrlImg=mc.obj.UrlImg

		mc.image_mc.loadMovie(UrlImg)

		mc.onRollOver=function(){		

		

			RollOver(this.obj)

			

			}		

		mc.onRollOut=function(){

			

			RollOut(this.obj)

			}

		

	

		

		 }

	}

function RollOver(obj){

	intervalROver=setInterval(IntervalRollOver,1,obj)

	

	

		}

function RollOut(obj){

	intervalROut=setInterval(IntervalRollOut,1,obj)

		}

	

function IntervalRollOver(obj){

	

	if(obj.mc._xscale<100){

		

		

		obj.mc._xscale=obj.mc._yscale+=a

		obj.mc._alpha+=a

		}

	else{

		clearInterval(intervalROver)

		}		

	}	

function IntervalRollOut(obj){

	if(obj.mc._xscale>50){

		

		obj.mc._xscale=obj.mc._yscale-=a

		obj.mc._alpha-=a

		}

	else{

		clearInterval(intervalROut)

		}	

	}

// End of code
