Web browser control does not display data in WPF window if window's allow transparency is true

Windows from have web browser control since .net 2.0, WPF also introduced a browser control from .net 3.5 sp1, well the controls are very good as far as functionality is concern, i my self prefer windows forms browser since it have more control with the functionality.

Today i encountered with a strange problem, in one of my application i used a modal dialog to present data as light box effect, inside the modal i added a browser control and then populated appropriate data, when i run the application the modal showed up, but the browser was just blank, no data what so ever. Later after few trial and error i found that my modal windows allow transparency property is set to true,  when i turned it to false, browser's content showed up.

Its a small problem perhaps many of you already knew about it, but since it killed almost two hour of my time, i thought its worth sharing. Happy coding..
