Pages '09 no longer will access dictionary/thesaurus in "writing tools"
I got Pages from the App Store last month. I got the upgrade just before Lion launched. I installed Lion. All worked fine til yesterday. Then Pages stopped accessing the dictionary/thesaurus in "Writing Tools." Then I had quite a few crashes -- some other settings like my Desktop changed. I can boot up and didn't lose any data that I know of. Any suggestions about linking the dictionary/thesaurus to writing tools as it was meant to? Thanks!
