Microsoft products are really weird

One of the programmes I love most is Microsoft Word. Everytime I __must__ write documents with Word I'm wondering why Microsoft didn't achieve it in over 10 years of development to make a product where the basic features work. Today I worked on an document that is entirely in english and I copied a small paragraph to insert it some paragraphs above. After pasting this paragraph a nice dialog poped up that says that the french language pack isn't installed, and I should installed it. I don't know why word changes the language of the insert paragraph to french. The worsted thing a program could to is to domineer the user. Microsoft products are really weird, so thats why I'm a fan of Linux and Mac.
