Hi!

OK, I figured out how to add a timer. Unfortunately, that does not 
help with my problem of the misbehaving field editor.

- (void)viewDidMoveToWindow
{
   [super viewDidMoveToWindow];
   
   self.focusTimer = [NSTimer timerWithTimeInterval:1.0
                                             target:self
                                           selector:@selector(focusOnSearchField)
                                           userInfo:nil
                                            repeats:NO];

   [[NSRunLoop currentRunLoop] addTimer:self.focusTimer 
forMode:NSEventTrackingRunLoopMode];
}

- (void)focusOnSearchField
{
   [[self window] makeFirstResponder:searchField];
   
   [self.focusTimer invalidate];
   self.focusTimer = nil;
}
