I'm taking a Latin language class in a location that does not have WIFI access.
On my Google Nexus 10 tablet with the Verbum application, I use the Dictionary of Latin Forms. I've discovered that without Internet access, any search within this document returns the message "reference not recognized", but if I'm able to have an active Internet connection (via an access point on my phone) then the search completes correctly.
With that document downloaded to my device, why would I need an active Internet connection in order to search withing said document?
