1. Prior to installing Office 2011, I ran Font Book. No conflicts were noted. All fonts were validated. 2. I then installed Office 2011 and all Office updaters. 3. I then checked Font Book again and discovered about 12-15 cautions. So I clicked on the Resolve button. 4. Then I started having a myriad of keyboard issues. Clearly, I messed things up when I tried to clear-up the cautions noted in Step 3 above. So I then reverted to a backup volume that did not contain Office 2011, and all is again as it should be. I would like to reinstall Office 2011 on my Lion volume, but before doing so, would appreciate your thoughts as to what I should do this time to avoid my earlier issues.
