My A1000 lenovo tablet stops responding whenever you close a app?

The tablet works fine when you first open it, as well as running the app. When you go to leave the app (via the home button) the tablet slows down significantly. After a minute or so, a message pops up saying "Ideadesktop isin't responding". Is there a fix to this? Or does anyone know the reason that this is happening?

We have the same tablet, i didn't happen to me. But there's a way to fix it try reinstalling android if that dosen't work you want to change out the whole motherboard or just send it back to lenovo support and get a new one.
