Swing freeze
I have developed a free software under the MS Flight Simulator (FS). It runs during the flight and records information about that. It will work fine as you can see on these pictures below:

This is when i want to close the application (works normally):

Of course sometimes it is necessary to switch from FS to that logger with alt+tab. It works fine.
But when I switch on the Anti Aliasing or Antisotrop Filtering, the whole application freezes when i switch from FS with an alt+tab:

The program refreshes fine until I switch to FS.
The program doesn't crash because if i would like to close the program, it will ask that question, but I see nothing:

It reacts the keyboard events correctly. If i press tab and then space at this question the program exits. I tried to refresh (revalidate, repaint, paintall, paintcomponents) but no results. If I start a Thread which repaints it every seconds then sometimes I can see the GUI but i can't enter any data.
Does anyone have a hint?
Thanks for advance.

Here is the code. Nothing special :)
public class Test {
public JFrame f;
private Container content;
public void init(){
f=new JFrame();
f.setTitle("TEST");
content=f.getContentPane();
content.setLayout(new BoxLayout(content,BoxLayout.Y_AXIS));
content.add(new JLabel("This is a text message"));
content.add(new JButton("TEST"));
content.add(new JTextField());
f.pack();
f.setVisible(true);
//new refr(this).start();
}
public static void main(String[] args) {
Test t=new Test();
t.init();
}
}

Point 1) When posting code, please use code tags. You can find out about them [url=http://forum.java.sun.com/help.jspa?sec=formatting]here[/url].
Point 2) Does your posted code reproduce your problem? I ran your code, and except for displaying a test JFrame with a textbox, message, and button, it does nothing. If it does reproduce your problem, how and when does it occur? If not, why post this code?
Good luck

ps: is your mini-app supposed to freeze after "alt-tabs"? Mine doesn't.

Point 1) Sorry for the code formatting. I was in hurry :(
Point 2) I could reproduce it after an alt+tab with Flight Simulator.
- maybe it is the bug of the simulator.
- maybe it is an NVidia bug.
I don't know it can be reproducable with other programs. It can be good if you have this one :).

sorry, I didn't read initial post carefully enough. I have neither an NVidia card nor the Flight Simulator, and so I'll bow out. Good luck!

It doesn't work :(
But...
I made a new Tread which calls the JFrame's paintAll method in every second. Of course I see nothing after the alt tab. But when i move my mouse over the application's icon on the tray and the tooltip is displayed I can see the JFrame window, and i can enter characters. But as soon as I move the mouse away from the tray, the JFrame freezes again. I have the same situation when I click the application with the right mouse button:

From this point I think it is not the Java fault. But if someone still has an idea please post here.
Is there a way to set the JVM Graphical engine (e.g. software or hardware rendering or something like this)?
