Wrong alt processing during switching between windows.

Regression test test/javax/swing/plaf/windows/WindowsRootPaneUI/WrongAltProcessing/WrongAltProcessing.java fails because of incorrect point coordinates for mouse click.

line 79:
    robot.mouseMove(point.x + (frame.getWidth() / 2), point.y + 5);

On windows 7 mouse clicks on hide button and test fails.
X-coordinate mast be on the left from hide button.
For example:
    robot.mouseMove(point.x + (frame.getWidth() / 2)-50, point.y + 5);
