Loss of keyboard focus in Java appl running under linux
I have a small sample program that replicates my problem. When this program is run a window is created. If you select File->New another instance of the program window is created. Now if you try to go back and bring to front the first window, keyboard focus is not
transferred when run under linux. You can only type in the second window. The expected behavior does happen in Windows.
