2.setExtendedState of the frame to Iconfied.
3.and make it visible.
4.Create a Window as a child of the frame. with a focusable button.

This defect exists in Windows since 5.0, i tried the same thing on dialog it works fine.

EVALUATION When the owned is not shown on the screen its owned window can't be focused. This follows from the javadoc: ------------------------ Window.isFocusableWindow <...>For a Window which is not a Frame or Dialog to be focusable, its focusable Window state must be set to true, its nearest owning Frame or Dialog must be showing on the screen, and <...> ------------------------ Also, I've found that the Window.isFocusableWindow() returns true after the Window is shown in the testcase. This should also be fixed.

EVALUATION When I press the button in the window, it is repainted as if it had focus. However, no key events are sent to it by Windows (I have verified this with Spy++). I think the best way to fix this problem is to restore the parent frame when its child window is shown or minimize the window if its parent is iconified.
