Calibre problems that aren't - Dictionary lookup

[YangonBill]

I tend to update calibre whenever possible... (remember Yangon is in Myanmar which has terrible internet connection). I noticed in one of the recent updates that they had included the ability to declare a dictionary for lookup. Subsequently I was re-reading Dune Messiah and came to a word that I wanted to check. Highlite, right click dictionary lookup... and results are in Portuguese (my spanish is bad and my portuguese is even worse). So I assumed it had to do with the update, and spent about an hour investigating how to change dictionary lookups... when I thought to check another book. Bottom line, even if the book is written in English, if the metadata says it is Portuguese, that is what wiki will be started in. Typical - user error.
