Hi,
I did work on MessageBox and finished a partial implementation, but
there are still some missing features like icons and MessageBoxOptions
handling. Anyway you can use it to display a message and retrieve a
response from the user, all buttons are working. The only really
missing thing is the icons.

See attached file :)

Bye.
