MI-L resizing Message Window

[Christophe Brabant]

Hi
 
I want to set position and size of the Message Window, different than the
defaults. (Set Window .......)
And I want ta place this window into the bottom right corner of the screen
too.
 
How should I calculate the position x and y, depending of the size of the
screen and the video resolution used ?
(it should work with 21 or 17 inches screens, and with 1024x768 and
1600x1400 etc...)
 
Thank you - Christophe
