Basic About dialog (nothing fancy)
You can have a black background(via mdx.dll which you can change the color around easily) or basic theme background.

I left the icon in it so you can place the info there (i.e. images\background\about.bmp)

Hope this helps

alias about { dialog -m about about }
dialog about {
  title "About"
  size  -1 -1 420 180
  text "PUT TEXT MESSAGE HERE "1,15 5 250 150
  icon 9,267 8 150 150, IF YOU HAVE A BACKGROUND IMAGE YOU CAN PUT IT HERE IF YOU WANT.
}

""""""""""""""""""""""""""""""
If you want the version with the black background use this (YOU MUST HAVE A MDX.DLL ALREADY)

dialog about {
  title "About"
  size  -1 -1 420 180
  text "PUT TEXT MESSAGE HERE "1,15 5 250 150
  icon 9,267 8 150 150, IF YOU HAVE A BACKGROUND IMAGE YOU CAN PUT IT HERE IF YOU WANT.
}
on *:dialog:about:*:*:{
  if ($devent == init) {
    $mdxin
    dll $mdx SetMircVersion $version
    dll $mdx MarkDialog $dname
    dll $mdx SetDialog $dname BGColor $color(1)
    dll $mdx SetColor $dname 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 background $color(1)
    dll $mdx SetColor $dname 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 textbg $color(1)
    dll $mdx SetColor $dname 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 text $color(14) 
  }
}
