Carolyn recently bought Office 2010 with 3 licenses. She installed it on her new lappy,and I installed it on my desktop. On Sunday eve I tried to open the attachment in Frankies 'To you ALL' post-it opened in Notepad and not Word. Carolyn then opened it on her lappy-it opened in Word as it should. I have re-configured Word (winword /r)-no change. I got Carolyn to send me a Word doc which opened as it should. So.......HELP !! Can anyone explain what's wrong and offer a solution? Mike.
