Some users have reported that the default Apple Dictionary widget stops working after updating their Macs to either Lion (10.7 onwards) or even Mountain Lion (10.8 onwards).
What do we mean by “stopped working”?
You enter your query word into the Dictionary widget text field as you normally would and then – nothing happens, or the widget jiggles around like its constipated. Wants to produce the dictionary meaning for you but for some reason unbeknownst to you, it simply can’t…
Some troubleshooting sites have suggested the atypical ‘go-to-solve-it-all’ methodology of hunting down the related OS X preference file and deleting it. In this case, com.apple.dashboard.plist file which can be found in ~/Library/Preferences/.
Nine out of ten times, for this particular issue at least, the above suggestion does not cure.
Surprisingly, the actual cure is profoundly simple… for an unknown reason the Dictionary widget has ‘compressed’ itself and just needs a little shaking up from us to resume its standard operation.
All that needs to be done is to hover your mouse over the area highlight in red above until the scroll cursor appears, then simply click and drag the scroll cursor downward. Which will reveal the regular text part (yellow notepad like page) of the Dictionary widget.
Once, you have successfully done that, you can attempt to query your first Dictionary word to test the widget’s response. Barring any unexpected hindrance, the Dictionary widget should resume its regular function.
