Okay... now I'm having a brand new issue I have NEVER encountered before. Obviously it's something of a new program (updated? option?) that highlights in light blue certain terms that "it" has a definition for... even in the arcade it's doing this to parts of the game names.

Where to look for this one?

never mind. I right clicked on one of the definitions and saw something referring to yahoo...that's the search engine I use... so in the options it has "show suggestions" and that was it! Whew.
