(update) The exception I mentioned in the previous post results when
an unfocused, alwaysOnTop, palette is visible. When Help closes, I
guess AppKit tries to return focus to an alwaysOnTop window by default
(?). It succeeds and then leaves a java app in a state with two
focused looking titlebars.

Because the help menu contains a keyboard focused search box, I
understand that when it is invoked, AppKit must send a window focus
event to the (Java) application. Am I correct in assuming that Apple
has done something behind the scenes to prevent Window titlebars
from repainting as unfocused iff the help menu is open?
From this follows the question: is there any way to detect the help
menu being displayed so that focus related repaints can be aborted?
I imagine this will get back into the distinction Apple makes
between 'key' and 'main' windows that doesn't translate to Java.

On a side note, the following non-fatal exceptions are thrown when
the help menu closes...
