Why does it freeze at 5th time??

Question

Hi,I never used JDesktopPanes and JInternalFrame so maybe I'm missing something important...
I got the following code:
private synchronized void refresh(){
        myDesktopPane.removeAll();
        MyData[] data=dataStructure.getData();
          for(int i=0;i<data.length;i++){
            JInternalFrame temp=new JInternalFrame(Integer.toString(data.getAnInfo()),true,true,true,true);
myDesktopPane.add(temp);
temp.setVisible(true);
}which is internal to an interface method:public void methodOnAnEvent(){
//changes dataStructure's data...
refresh();
Basically when the event occours data in dataStructure changes,so a window refreshing is needed and refresh() method is called.
Old internal frames are destroyed with removeAll() method and new internal frames are created and added to desktop pane.
Strangely everything goes right till 5th time same event is received,so:
1st time: internal frames are updated.
2th time: ok
5th time: EVERYTHING FREEZES!
I did several tries and it's always at 5th time...what could it be??

I did several tries and it's always at 5th time...what could it be??You've got a bug somewhere, but I don't see it in the code you've posted.
I'm curious why the refresh method is synchronized and not called on the EDT, the event dispatch thread?
