Abstract
A method and apparatus for re-drawing a transparent window on at least one display device of a computer based system having a central processor and a memory is disclosed. Having a transparent window and an underlying second window, it is determined whether the underlying second window is active. If the underlying second window is active, the transparent window is hidden. The underlying second window is re-drawn and the transparent window is shown. Otherwise, the transparent window is maintained.
