Because the Dialog class inherits from Window, you can size it 
with setSizeRequest(). On Windows, at least. I'm not sure about 
Linux. I'm about to go out for a few hours, so perhaps you could 
test this.

That's another topic I have on my list for the dialog series.

It's because there are two flags controlling resize-ability, both 
found in generated\gtkd\gdk\c\types.d:
- a window decorations flag (GdkWMDecoration), and
- another that controls whether or not the window is allowed to 
resize (GdkWMFunction).

If the programmer turns off the resize flag, but not the 
decorator flag, well... there's your answer.

Hope that helps, number.
