Thanks for your reply.
1. The text that I'm trying to insert has paragraph spacing before & after set to auto, but my doc has it default to 0, so every single time I inserted a text, I had to highlight the inserted paragraph and remove manually the spacing before and after.
2. Thanks for this tip. Is there anyway that I can tell Word NOT to insert styles from other docs/sources?
I've noticed that after few pastings, I had quite a few Normal (web) styles in my style list, and it keeps growing when I try to insert new texts from web pages.

ps: the way I'm inserting texts into my doc is this:
1. I highlight the text I'm interested in webpage
2. copy/paste into Notepad (which is supposed to remove all formatting from the text)
3. cut/paste into my doc, but still the style get through to my doc, it only removed bold/url references, etc. but not style!!! Is there any other way to do it easier? Is there an editor which REALLY removes ALL formatting?

Thanks for your suggestion/comment
