There is a well known issue with MacBook Pros (circa early 2007) in
that they lose keystrokes. Apple even released a fix for it after
volumes of complaints - it helped a little, but the issue still
persists. I've convinced myself it's a design flaw they can't fully
remedy. So the big question is - are you using a MacBook Pro of that
vintage?
In the first place, no, this is a 2008 MBP.
In the second place, it is not a keyboard-hardware problem. It is
entirely clear that the software thinks it is losing focus, because
the window highlighting changes to the not-focused state; and then
back again a moment later. Or sometimes not --- I have also seen
it drop focus from all windows and stay that way until clicked on.
X11 remains the foreground app throughout, or at least I never see
any change in the menu bar to suggest differently.
I've seen an icon quickly flash into the dock and then leave when I've
seen this occur, and it happens with other applications in the
foreground (it's happened to me when using Terminal.app).
Therefore, I'm convinced there is NOTHING we can do in X11 to fix the
problem. There may be a way to turn on logging in the window server,
so you can determine what process is stealing the focus...
The thing that has gotten markedly worse in rc5 is that sometimes
(often) when the focus comes back, it is reassigned to a different
X11 window than before. I do not have a clear pattern as to which
one gets focus instead. It's not as easy as the one under the mouse
(if it was, the usability hit wouldn't be nearly so bad). I thought
for awhile that it was going to the latest-created window but I
think I've seen counterexamples to that theory.
I haven't seen this. In fact, I've tested with the current build
(post 2.3.3_rc5), and I can't reproduce this behavior. Every time I
reactivate X11, the last-focused window is the one that regains focus...
And yes, I've got focus-follows-mouse on.
Ah... that's the missing key I was missing. There were some issues
with mouse tracking while X11 was in the background. That was fixed
after 2.3.3_rc5. Hold tight and 2.3.3 will have your fix. We're just
waiting on the OSX 10.5.7 update to be released.
