George,
The MS Docs do not say that at all. I quote:

"BS_NOTIFY Enables a button to send BN_KILLFOCUS and BN_SETFOCUS
notification messages to its parent window.
Note that buttons send the BN_CLICKED notification message regardless of
whether it has this style. To get BN_DBLCLK notification messages, the
button must have the BS_RADIOBUTTON or BS_OWNERDRAW style.
"

It talks about focus notification, not click notification.

But back to your problem.

Can I suggest you use win32lib's create(Radio, ...) instead, and then use
the click handler for all your buttons. Something along the lines of :

  sequence radiobtns, tags
  radiobtns = {}
  tags = {}

  id = create(Radio,EUmenu[i][j][1],subMenuId[i],col,row,lenRow,20,0)
  if length(tags) < id then
    tags &= repeat(0,id - length(tags))
  end if
  tags[id] = {i,j}
  radiobtns &= id
  .
  .
  .
  procedure ClickRadio(integer self, integer event, sequence parms)
     -- You can then use tags sequence to quickly get the
     -- original 'i' and 'j' values.

     integer oi, oj, win

     oi = tags[self][1]
     oj = tags[self][2]

     -- Get which window was just clicked.
     win = subMenuId[oi]
     . . .
  end procedure
  setHandler(radiobtns, w32HClick, routine_id("ClickRadio"))
