ComboBox delete from memory

Question

Hi
Have got page where many times add/remove combobox. Unfortunately in cases when 'user':
1)add text to TextInput
2)'interact' with combobox
Profile is showing that instance of class ListCollectionViewCursor is not removed. But when there is no any of above interaction instance of class ListCollectionViewCursor is removed
Simple test :
1) when page loaded click 'remove combobox' - you will see that ListCollectionViewCursor is removed
2) when page loaded add some text to TextInput then click 'remove combobox' - you will see that  ListCollectionViewCursor is not removed
What I am doing wrong?
CODE:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
    <![CDATA[
        private function remove():void{
            if(_combobox !=null){
               _container.removeChild(_combobox)
               _combobox = null;
            try {                   
                   new LocalConnection().connect('foo');
                   new LocalConnection().connect('foo');
                } catch (e:*) {}
    ]]>
</mx:Script>
<mx:VBox id="_container">   
    <mx:HBox>
        <mx:Button click="remove()" label="remove combobox" />
        <mx:TextInput id="_textFocus"/>
    </mx:HBox>
     <mx:ComboBox id="_combobox"   width="265" height="33" >
         <mx:ArrayCollection id="_comboboxAC">
             <mx:String>text</mx:String>
             <mx:String>text</mx:String>
         </mx:ArrayCollection>
     </mx:ComboBox>
</mx:VBox>   
</mx:Application>

Thanks for your responses. I'll go ahead and use "Import photos from disk" and change to my card reader. I personally had no problems in my years reading & immediately deleting files from memory cards. I had a few instances where I inadvertently deleted a fresh imported picture on the computer, I used undelete utilities on the card in these cases.
That said, I still think it would be a good feature. If the users want to do it (2 years of questions), just let them.
