Returning to a search result with "back" button closes app

[Foxdelmar]

Hi, thanks for your app. I use it a lot but there is thing that could be improved:

When I open a german-german dictionary and open "Salz" and then tap on a text which is underlined like "einen Scheffel Salz mit jemandem essen", it shows a new search with no results. From this view I am not able to get back. If I use the android button to go back the app just closes.

Could you correct it in a way that the app saves the history and brings the user always back to the last view?
