JFileChooser in Applet hangs ie7 and vm

Question

Hello
First of all, excuse my poor english.
In my website I have a problem with an applet.
This applet is used to select files from the client computer.
My JRE version is 1.5.0_10 Java HotSpot(TM) Client VM
The browser is IE 7
The OS is WinXP SP2
First time the page is loaded works fine, but when the page is reloaded it crashes when it makes a new instance of JFileChooser.
This hangs the ie and the vm.
I've tried it in other computer that uses the 1.5.0_07 and ie 7, and it works fine.
This is the code:
shpFileChooser = new javax.swing.JFileChooser();
shpFileChooser.setFileSelectionMode(javax.swing.JFileChooser.DIRECTORIES_ONLY);
int retOutbox = shpFileChooser2.showOpenDialog(null);
if(retOutbox==JFileChooser.APPROVE_OPTION){
path = shpFileChooser2.getSelectedFile().getPath();
else {
path = "";
Please Help me.

I'm also have the problem with JFileChooser spiking the CPU in an applet -- with JRE 6 Update 2, which I just installed (did not happen with Update 1).
When new JFileChooser() is hit, the CPU usage spikes to 100% for about 15 seconds until the control appears. Then as I navigate through folders, I get a similar spike for each click.
This is happening for both IE7 and FireFox 2.0.0.5 on WinXP SP2.
Any insights are much appreciated.
