[MACTCL] Weird Window Behavior

[Will D. <wi...@wj...>]

Howdy!

This is something weird I've seen using Active Tcl 8.5 on
Mac OS X 10.5.1 (Intel) while working on Notebook.  I've not been
able to come up with a simple case that shows the error, yet, but
it occurs in the version of Notebook that's in my svn repository,
http://notebook.wjduquette.com/repos/notebook/trunk.

* I open Notebook, getting a Notebook Browser window.
* I open a second Notebook Browser window, on the same or another
   notebook file.
* I press the amber button in the titlebar to make the second
   window shrink down to the dock.
* I hide the entire application (Command-H).
* I reshow the entire application but clicking on the application
   icon in the dock.
* I reshow the second Notebook Browser window, by clicking on its
   icon in the dock.

At this point the odd things begin.  First, pressing Command-E
should open the editor for the current Notebook page, just as though
I selected the "Page/Edit" menu item.  It doesn't.  The "Page" menu
flashes on the menu bar, but the editor doesn't appear.  If I
select the menu item explicitly, however, it does.  But the editor
doesn't respond to the keyboard, and several toolbar icons are
missing in the editor.

My suspicion is that the application window isn't receiving or
accepting the keyboard focus as a result of the scenario I
describe.  I've got a system of user interface "actions" in
place that determines whether menu items, key commands, and
toolbar buttons are available or not based on a number of factors,
including which widget has the focus.

This didn't used to happen, so far as I know; I suspect it's a
Leopard thing.

If I can put together a simple example, I'll post it here and
on the Tk bug tracker.
