Well, the problem is solved. The program was showing me grammar and word
definition of every English word I hovered my mouse over. When the word was
non-English the program was showing me its inability to find the word in the
French dictionary. As soon as I move the mouse from the word the background
image disappears. The most annoying part was that I am writing a biography
where most of the information available is in German, so the program can
look till the cows come home for non-English words in the French dictionary,
it is not going to find them.
Someone contacted me off-line and offered the following:
Under 'review' select 'translate' and then 'mini translator' and unselect
Now I can hover to my heart's content and nothing shows in the background.
