Summary: Possible focus bug in Aqua Tk 8.4.2

Initial Comment:
There is an apparent focus bug in Aqua Tk 8.4.2 running on MacOS X 10.2.6.

- Run the following code (which started as a pop-up help system
  but has been stripped down to just show the bug).
- Click on the entry widget, so it received focus
- Move the mouse a bit within the entry widget,
  so the pop-up help window is displayed.
  (Make sure the mouse is not over where the help window
  pops up else it will go away instantly.)
- Type one or more characters.
- On MacOS X the code *claims* that the entry widget .e still has focus
  but this is a lie. Keystrokes are actually ignored,
  and it seems likely they are going to the pop-up help window
  instead of the entry widget that allegedly still has focus.

Notes:
- Adding code that tells Tk to return the focus to the entry
  does not help. One still cannot type in the entry widget.
  Maybe this is not surprising, since tcl/tk seems to think
  the entry widget already has focus.
- The code runs fine under my unix setup:
  (unix Tcl/Tk 8.4.1, MacOS X 10.2.6, Apple's X11 beta 3),
  BUT it starts failing in a similar way if I remove the
  "wm overrideredirect" command.
- Thus perhaps the bug is more pervasive than MacOS,
  and/or it's not a bug and I'm going about this all wrong.
 

entry .e
pack .e

bind .e "<Motion>" {
	destroy .t
	puts "show help; focus is [focus]"
	toplevel .t
	wm overrideredirect .t 1
	wm transient .
	message .t.m -text "this is a help msg"
	pack .t.m
	puts "help is showing; focus is [focus]"
}

bind .e "<Leave>" {
	puts "leave"
	destroy .t
}

bind .e "<KeyPress>" {
	puts "keypress"
	destroy .t
}

This is a dup of 1124237.  Same fix for that bug fixes this as well.
