I think this helped me to realize what is happening. I am not quite sure but
I believe this is a good guess:
*** This is where the tooltip window gets created (I did not check further
to see if it where reused, but the timings suggests to me it is not):
>>>> w32fns.c >>>>
void
my_create_tip_window (f)
struct frame *f;
{
...
tip_window = FRAME_W32_WINDOW (f)
= CreateWindow (EMACS_CLASS,
...
FRAME_W32_WINDOW (SELECTED_FRAME ()), /* owner */
...
NULL);
...
}
*** There is a SELECTED_FRAME above. As far as I understands it
SELECTED_FRAME is set by operations that Emacs recognize.
*** Emacs does not recognize Alt-Tab. This is the real problem and the case
we have here is just a special problem with its root in this.
I actually wrote about this when we discussed "Popup when buffer file is
changed on disk" which Moheb brought up. I implemented some code to take
care of this (but maybe it was on the wrong level).
I would suggest taking care of the message w32 sends when the user press
Alt-Tab. (This is some kind of "got focus message", but I do not know the
name at the moment.) The best would IMO to make a hook that is run when the
message is received. It could then be used to solve problems like "Popup
..." above too.
I am a bit surprised that this does not seem to happen on other platforms.
Or does it? I can not understand why, can anyone explain?
