Hi, I have a trouble with my Office Word 2010. I can not look up new words in Word 2010. In the past, I often Ctrl+Right Click to get new words' meaning at once, but when I installed the Window 7 (64bit) because my RAM was upgraded to 4GB, I can not do as I used to. When I Ctrl+Right click, it appears a pop-up "Make your selection first". My laptop is using Win7 64bit at the moment, but it still can look up new words'meaning when I Ctrl+Right Click. Do you know what happened with my PC yet? Thanks so much! Ps: I use another software to help me look up meaning.
