Just thought it would be fair to mention, check if your dictionaries are out of date and update them. My JMDict is updated daily, so I don't have to worry about it. Yomitan doesn't have this by default so I recommend updating JMDict every few months. The amount it's changed and improved from just 1 year ago is fairly massive. A lot of improvements overall that many can benefit from. Sites like jisho.org pulls from JMDict daily.
Here's a link to Yomitan JMDict daily update releases:
