Hola Pazos,
Yes, I am still using FW10 on Tolino, due to refresh issues with Coolreader,
and now I saw you added support for external dictionaries and I thought, I could try to integrate my spanisch-slovak dict with koreader like I did for coolreader as I think it has better rendering due to further development of crengine ...
I could upgrade my test Tolino for later FW with Android 4.4.2, but curently I am facing similar issue you referenced here and wrote in github comment that was solved (I described my behaviour also there ... )
