Description

The attached code creates JFrame with transparent background and opacity set to 0.9f. On Windows Vista Aero the window is shown with title and border but these elements are not clickable. Clicks are received by underlying application.

Comments

EVALUATION I reproduced the problem and attached the screenshot, the window seems to have the decorations but they are not clickable and disapear after you activate another application and then go back to the test I didn't find the requirement that a window must be undecorated to support transparency accepted and reassigned to AWT
