It does seem that any input prevents these focus problems, so it is possibly a case of a message being sent between the UI and Lisp threads, but not getting processed until input arrives. --------------000009080007050308010408 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Lennart Borgman wrote:

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.
It is probably a bug if focus gained messages from the OS do not set the selected frame, but no new Lisp hooks should be needed.

It does seem that any input prevents these focus problems, so it is possibly a case of a message being sent between the UI and Lisp threads, but not getting processed until input arrives.
