Why is it incorrectly ? What would you like?

Remember that Word is not an internet application but a desktop wordprocessing program that has many more options then what is even possible on internet, internet is a totaly different language where options are way more limited.

You can use past special or past normal to see if this takes effect. If you want to lose the format from text completly (the format from word is usualy copied allong with the text) you can use notepad as medium to lose these settings and get plain text so the internet text options set in x5 will do the rest.

Word has also many versions, and there are beside Word many other word processing programs, that work just a little bit different from eachother. This makes things complicated and difficult to adjust in x5.

So best way is to go back to plain text with notepad for instance and then set the format that can be used for websites for the best possible view for your visitors in X5.

This garanties a good viewable website for all viewers, with all of there own software (here -on the other side the viewers side-  are also great differences, think about mobiles, tableds, differents O.S. and different webviewers, different lettertypes installed on pc's and so on...)
