Hi guys,
OK, for those interested, I've got the "World's biggest encyclopedia" to work as a lookup dictionary from other books, finally. It wasn't working because of a bug in the new firmware:-
The user can either have a dictionary on CF card searchable from other books OR can open it and search inside it, but lose the ability to search from other books. This was the problem - I had already opened the encylopedia therefore it was not searchable. It seems that the PRC on CF card must be in the mobipocket directory, not a sub-folder, hence the problem. One work around is to have two copies and never open one, but since the encylopedia is 200mb this might be stretching things
