Hi, I have a problem with my java 3D applet. When I am testing my Java 3D applet on my laptop with windows 98, everything is fine. However, when I copied the same files to my desktop with windows 2000, and tested it, everything is fine except that when I open a dialog window, and close the window, I got a big grey ugly hole on my screen. The frame window doesn't repaint itself automatically. I used repaint() to force the window to repaint, it didn't work. But if I rotate the object, then the dialog-window-size ugly hole is gone. My questions are: what can I do with this problem? Is it a windows 2000 problem? Do I need to change some configuration in windows 2000 to force repainting? My laptop: PII 366 with 128M memory, windows 98 second edition, jdk1.3 and java 3D 1.2(OpenGL) My desktop: PII 400 with 256M memory, windows 2000 with serice pack 1, jdk1.3 and java 3D 1.2 (OpenGL) Thank you Qiuli Sun =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
