Is their an archive of this mailing list floating around on the web 
somewhere???  I wouldn't mind checking to see if questions I ask have 
already been answered before I ask them.  thanks

I just changed the
      :best-width (/ capi:%width% 2)
with
	:best-width capi:%width%

As I want the mdi child windows to exactly fit into its parent. However, the
actual child is a bit larger than the mdi container. How can I get the exact
size ? How does "windows/tile horizontally" do its calculation ?

Thanks,

You could simply make the child with :DISPLAY-STATE :MAXIMIZED.

We don't currently provide a way to get the external size of an
interface.

Another issue is that the MDI container can have scroll bars, so it
doesn't really have a fixed size.

Windows does this, in response to the WM_MDITILE message. I don't see
any documentation about how the calculation is done.
