Hi, In my code implementation, I designed a frame with my specified minimized icon. But when I implemented the code on IBM AIX 4.3 platform with jre version 1.3.0, But when the frame is iconized, it shows java icon instead of my specified one. After debugging, I found that the icon is correctly loaded with the right image, and the frame is set with this icon image. What's the reason that I cannot get the right icon when the frame is minimized? Also, the problem is not cross platform, just on IBM AIX. Thanks.
