Hi Barry,
so is double click in Word still NOT working while the double click in another application such as the text editor here on the forum is working ?
If that is the case, I would dig up your product ID from your Office Install and completely remove it per instructions, then reinstall Office and then upgrade to current release. See some steps:
1 First be sure you have a current BU of your Mac.
2. Then your Office 2011 DVD with the product key #.

)
3. Then remove Office according to MS instructions

4. Reinstall Office 2011
5. Enter your Product #
6. Once Office 2011 is installed, update Office by going to Help menu within Word or Excel or PowerPoint and select Update.
7. Have a nice cold beverage !
The latest version of Office 2011 for the Mac is 14.6.3
