The error-failed to set window into focus

greetings,

I am getting an error:
failed to set window ‘{:index=>0, :hwnd=>134611314}’ into focus!
Whats the meaning of that? any solution?

Context!

At a guess I’d say you’re firing an event which requires window focus in
order to work properly, and for some reason the focus has been stolen or
the application hasn’t been able to focus in order to fire the event.
This might happen, for example, if you’re using IE in concurrant
threads.
