Popup memory removement

Question

Hello,
we have to use many popup-windows with flex (flex 2.0). so we
create the flex-popupwindows with the addPopup and remove the popup
windows with, removepopup function.
we have now the following problem.
on every popup event the memory usage icrease (this is ok)
but on removing the popup, we dectect a "memory-leak".
if use the function a lot of time (creating 10 or more modal
popupwindows with an menubar) -- the memoryusage is very high, too
high. i have seen, some other users have the same or similar
problem with memorymanagement. I searched in some forums and
searchmachines , i get allways the same answert that the garbage
collector of flex and / or actionscript 3.0 (flash 9.0 player) is
great an removed obcject without references. we remove, befor
closing the popup all Childs... set the variable to null etc.. no
effect.
Our customers cannot work with this memory-leak, is there an
solution?
Btw: we have a memory-problemt with the menubar too, on
moving the mouse-cursor over the menubar the memoryusage is
increasing too.
Thanks for helping

Hey guys,
Do you have a code example for me please?
I am using the popup for a piece of code that takes some time
to run.. and when its done running i remove the popup. But when i
run the script again, my popup doesn't appear. :(
Here the code i use:
private var pop2:Canvaspopup;
public function imageSelected(event:Event):void // i cum
here on the select event from a file dialog box.
trace(pop2);
if(pop2!=null)
pop2=null;
pop2=new Canvaspopup();
pop2 =
Canvaspopup(PopUpManager.createPopUp(Application.application as
Sprite,Canvaspopup,true));
PopUpManager.centerPopUp(pop2);
// here i do some image stuff like use a loader for the
selected image
public function handleImageComplete(event:Event):void //when
the loader is complete i cum here
// do some image resizing and saving
PopUpManager.removePopUp(pop2);
pop2=null;
}
