Computer Freeze
843810Mar 21 2005 — edited Mar 22 2005My computer freezes when I restart a Java application.
First time I run the application I have no problems. I exit normally and restart the application. The computer freezes after the outer frame is displayed. The computer does not react to Ctrl-Alt-Del. Eventually the screen starts fading (gets white with two black vertical lines at the left). I have not noticed any similar behavior with any other applications.
The freeze only occurs on a laptop that runs Windows 2000 Pro. On another desktop running Windows XP Home, the problem does not occur.
The application uses Swing extensively. I did not notice the problem until I introduced BufferedImages into the program, so I don't know if that can be related to the problem. I dispose the graphics when done with them (also at exit).
The application was developed with netbeans 4.0 and J2SE 5.0 update 1. JRE is 5.0 update 2.
Can anyone give me a hint to what the cause of this problem may be?
